Rhamnolipid Biosynthesis diRL(14:1(3-OH,7Z)/14:1(3-OH,5Z))

Pseudomonas aeruginosa
Rhamnolipids (RL) consist of a fatty acyl moiety composed of a 3-(3-hydroxyalkanoyloxy)alkaloid acid (HAA) and a sugar moiety composed of one or two rhamnose sugars. Rhamnolipids function as surfactants and virulence factors and are involved in biofilm formation and cell motility. The rhamnose sugar component is produced via the dTDP-L-rhamnose biosynthetic pathway which forms dTDP-L-rhamnose from glucose 6-phosphate (G6P) in five steps. First, glucose 6-phosphate is converted into glucose 1-phosphate (G1P) via the enzyme phosphoglucomutase (AlgC). Second, glucose 1-phosphate is converted into dTDP-D-glucose via the enzyme glucose-1-phosphate thymidylyltransferase (RmlA). Third, dTDP-D-glucose is converted into dTDP-4-dehydro-6-deoxy-D-glucose via the enzyme dTDP-glucose 4,6-dehydratase (RmlB). Fourth, dTDP-4-dehydro-6-deoxy-D-glucose is converted into dTDP-4-dehydro-L-rhamnose via the enzyme dTDP-4-dehydrorhamnose 3,5-epimerase (RmlC). Fifth, dTDP-4-dehydro-L-rhamnose is converted into dTDP-L-rhamnose via the enzyme dTDP-4-dehydrorhamnose reductase (RmlD). The HAA component is synthesized from 3-hydroxyacyl-[acyl-carrier protein] diverted from fatty acid biosynthesis via the enzyme 3-(3-hydroxydecanoyloxy)decanoate synthase (RhIA). The final step in rhamnolipid biosynthesis is the formation of the glycosidic link between the rhamnose sugar component and the HAA component. This is accomplished by two rhamnosyltransferases (RhlB and RhlC) which catalyze sequential glycosyl transfer reactions to first form mono-rhamnolipids (via RhIB) and then di-rhamnolipids (via RhIC). RHlA, RHlB, and RHlC are associated with the inner membrane.

Lipopolysaccharide Biosynthesis III

Parabacteroides sp. D13
E. coli lipid A is synthesized on the cytoplasmic surface of the inner membrane. The pathway can start from the fructose 6-phosphate that is either produced in the glycolysis and pyruvate dehydrogenase or be obtained from the interaction with D-fructose interacting with a mannose PTS permease. Fructose 6-phosphate interacts with L-glutamine through a D-fructose-6-phosphate aminotransferase resulting into a L-glutamic acid and a glucosamine 6-phosphate. The latter compound is isomerized through a phosphoglucosamine mutase resulting a glucosamine 1-phosphate. This compound is acetylated, interacting with acetyl-CoA through a bifunctional protein glmU resulting in a Coenzyme A, hydrogen ion and N-acetyl-glucosamine 1-phosphate. This compound interact with UTP and hydrogen ion through the bifunctional protein glmU resulting in a pyrophosphate and a UDP-N-acetylglucosamine. This compound interacts with (3R)-3-hydroxymyristoyl-[acp] through an UDP-N-acetylglucosamine acyltransferase resulting in a holo-[acp] and a UDP-3-O[(3R)-3-hydroxymyristoyl]-N-acetyl-alpha-D-glucosamine. This compound interacts with water through UDP-3-O-acyl-N-acetylglucosamine deacetylase resulting in an acetic acid and UDP-3-O-(3-hydroxymyristoyl)-α-D-glucosamine. The latter compound interacts with (3R)-3-hydroxymyristoyl-[acp] through UDP-3-O-(R-3-hydroxymyristoyl)-glucosamine N-acyltransferase releasing a hydrogen ion, a holo-acp and UDP-2-N,3-O-bis[(3R)-3-hydroxytetradecanoyl]-α-D-glucosamine. The latter compound is hydrolase by interacting with water and a UDP-2,3-diacylglucosamine hydrolase resulting in UMP, hydrogen ion and 2,3-bis[(3R)-3-hydroxymyristoyl]-α-D-glucosaminyl 1-phosphate. This last compound then interacts with a UDP-2-N,3-O-bis[(3R)-3-hydroxytetradecanoyl]-α-D-glucosamine through a lipid A disaccharide synthase resulting in a release of UDP, hydrogen ion and a lipid A disaccharide. The lipid A disaccharide is phosphorylated by an ATP mediated tetraacyldisaccharide 4'-kinase resulting in the release of hydrogen ion and lipid IVA. A D-ribulose 5-phosphate is isomerized with D-arabinose 5-phosphate isomerase 2 to result in a D-arabinose 5-phosphate. This compounds interacts with water and phosphoenolpyruvic acid through a 3-deoxy-D-manno-octulosonate 8-phosphate synthase resulting in the release of phosphate and 3-deoxy-D-manno-octulosonate 8-phosphate. This compound interacts with water through a 3-deoxy-D-manno-octulosonate 8-phosphate phosphatase thus releasing a phosphate and a 3-deoxy-D-manno-octulosonate. The latter compound interacts with CTP through a 3-deoxy-D-manno-octulosonate cytidylyltransferase resulting in a pyrophosphate and CMP-3-deoxy-α-D-manno-octulosonate. CMP-3-deoxy-α-D-manno-octulosonate and lipid IVA interact with each other through a KDO transferase resulting in CMP, hydrogen ion and alpha-Kdo-(2-->6)-lipid IVA. The latter compound reacts with CMP-3-deoxy-α-D-manno-octulosonate through a KDO transferase resulting in a CMP, hydrogen ion, and a a-Kdo-(2->4)-a-Kdo-(2->6)-lipid IVA. The latter compound can either react with a palmitoleoyl-acp through a palmitoleoyl acyltransferase resulting in the release of a holo-acyl carriere protein and a Kdo2-palmitoleoyl-lipid IVa which in turn reacts with a myristoyl-acp through a myristoyl-acp dependent acyltransferase resulting in a release of a holo-acp and a Kdo2-lipid A, cold adapted, or it can interact with a dodecanoyl-[acp] lauroyl acyltransferase resulting in a holo-[acp] and a (KDO)2-(lauroyl)-lipid IVA. The latter compound reacts with a myristoyl-[acp] through a myristoyl-acyl carrier protein (ACP)-dependent acyltransferase resulting in a holo-[acp], (KDO)2-lipid A. The latter compound reacts with ADP-L-glycero-beta-D-manno-heptose through ADP-heptose:LPS heptosyltransferase I resulting hydrogen ion, ADP, heptosyl-KDO2-lipid A. The latter compound interacts with ADP-L-glycero-beta-D-manno-heptose through ADP-heptose:LPS heptosyltransferase II resulting in ADP, hydrogen ion and (heptosyl)2-Kdo2-lipid A. The latter compound UDP-glucose interacts with (heptosyl)2-Kdo2-lipid A resulting in UDP, hydrogen ion and glucosyl-(heptosyl)2-Kdo2-lipid A. Glucosyl-(heptosyl)2-Kdo2-lipid A (Escherichia coli) is phosphorylated through an ATP-mediated lipopolysaccharide core heptose (I) kinase resulting in ADP, hydrogen ion and glucosyl-(heptosyl)2-Kdo2-lipid A-phosphate. The latter compound interacts with ADP-L-glycero-beta-D-manno-heptose through a lipopolysaccharide core heptosyl transferase III resulting in ADP, hydrogen ion, and glucosyl-(heptosyl)3-Kdo2-lipid A-phosphate. The latter compound is phosphorylated through an ATP-driven lipopolysaccharide core heptose (II) kinase resulting in ADP, hydrogen ion and glucosyl-(heptosyl)3-Kdo2-lipid A-bisphosphate. The latter compound interacts with UDP-alpha-D-galactose through a UDP-D-galactose:(glucosyl)lipopolysaccharide-1,6-D-galactosyltransferase resulting in a UDP, a hydrogen ion and a galactosyl-glucosyl-(heptosyl)3-Kdo2-lipid A-bisphosphate. The latter compound interacts with UDP-glucose through a (glucosyl)LPS α-1,3-glucosyltransferase resulting in a hydrogen ion, a UDP and galactosyl-(glucosyl)2-(heptosyl)3-Kdo2-lipid A-bisphosphate. This compound then interacts with UDP-glucose through a UDP-glucose:(glucosyl)LPS α-1,2-glucosyltransferase resulting in UDP, a hydrogen ion and galactosyl-(glucosyl)3-(heptosyl)3-Kdo2-lipid A-bisphosphate. This compound then interacts with ADP-L-glycero-beta-D-manno-heptose through a lipopolysaccharide core biosynthesis; heptosyl transferase IV; probably hexose transferase resulting in a Lipid A-core. A lipid A-core is then exported into the periplasmic space by a lipopolysaccharide ABC transporter. The lipid A-core is then flipped to the outer surface of the inner membrane by the ATP-binding cassette (ABC) transporter, MsbA. An additional integral membrane protein, YhjD, has recently been implicated in LPS export across the IM. The smallest LPS derivative that supports viability in E. coli is lipid IVA. However, it requires mutations in either MsbA or YhjD, to suppress the normally lethal consequence of an incomplete lipid A . Recent studies with deletion mutants implicate the periplasmic protein LptA, the cytosolic protein LptB, and the IM proteins LptC, LptF, and LptG in the subsequent transport of nascent LPS to the outer membrane (OM), where the LptD/LptE complex flips LPS to the outer surface.

Salvage Pathways of Pyrimidine Deoxyribonucleotides

Parabacteroides sp. D13
The pathway begins with the introduction of deoxycytidine into the cytosol, either through a nupG symporter or a nupC symporter. Once inside it is deaminated when reacting with a water molecule, a hydrogen ion and a deoxycytidine deaminase resulting in the release of an ammonium and a deoxyuridine. Deoxyuridine can also be imported through a nupG symporter or a nupC symporter. Deoxyuridine can react with an ATP through a deoxyuridine kinase resulting in the release of a ADP , a hydrogen ion and a dUMP. Deoxyuridine can also react with a phosphate through a uracil phosphorylase resulting in the release of a uracil and a deoxy-alpha-D-ribose 1-phosphate.

Thiosulfate Disproportionation III

Parabacteroides johnsonii DSM 18315
Thiosulfate sulfurtransferase (also known as rhodanese) can facilitate the transfer of a sulfur atom from sulfur donors to nucleophilic sulfur acceptors, and it has been found in many major phyla (prokaryotic and eukaryotic). The role of thiosulfate sulfurtransferase might be the detoxification of cyanide in both bacteria and mammals, or it might also involve in formation of prosthetic groups in iron-sulfur proteins. In this pathway, thiosulfate and hydrogen cyanide have been catalyzed by thiosulfate sulfurtransferase to form thiocyanate and sulfite. Sulfite is used in later sulfur metabolism.
