Palmitate Biosynthesis

Barnesiella intestinihominis YIT 11860
Palmitate is synthesized by stepwise condensation of C2 units to a growing acyl chain. Each elongation cycle results in the addition of two carbons to the acyl chain, and consists of four separate reactions. The pathway starts with acetyl-CoA interacting with hydrogen carbonate through an ATP driven acetyl-CoA carboxylase resulting in a phosphate, an ADP , a hydrogen ion and a malonyl-CoA. The latter compound interacts with a holo-[acp] through a malonyl-CoA-ACP transacylase resulting in a CoA and a malonyl-[acp]. This compound interacts with hydrogen ion, acetyl-CoA through a KASIII resulting in a CoA, carbon dioxide and an acetoacetyl-[acp]. The latter compound interacts with a hydrogen ion through a NADPH driven 3-oxoacyl-[acyl-carrier-protein] reductase resulting in an NADP and a (R) 3-Hydroxybutanoyl-[acp](1). This compound is then dehydrated by a 3-hydroxyacyl-[acyl-carrier-protein] dehydratase resulting in the release of water and a crotonyl-[acp](2). The crotonyl-[acp] interacts with a hydrogen ion through a NADH enoyl-[acyl-carrier-protein] reductase(NAD) resulting in NAD and a butyryl-[acp](3). The butyryl-[acp] interacts with a hydrogen ion, a malonyl-[acp] through a KASI resulting in a holo-[acp],carbon dioxide and a 3-oxo-hexanoyl-[acp](4).

Palmitoyl then reacts with water spontaneously resulting in a hydrogen ion, a holo-[acp] and palmitic acid. No integral membrane protein required for long chain fatty acid uptake has been identified in E. coli. The transport of long chain fatty acids across the cytoplasmic membrane is dependent on fatty acyl-CoA synthetase. An energised membrane is necessary for fatty acid transport and it has been suggested that uncharged fatty acids flip across the inner membrane by diffusion.

Cardiolipin (CL) is an important component of the inner mitochondrial membrane where it constitutes about 20% of the total lipid composition. It is essential for the optimal function of numerous enzymes that are involved in mitochondrial energy metabolism (Wikipedia). Cardiolipin biosynthesis occurs mainly in the mitochondria, but there also exists an alternative synthesis route for CDP-diacylglycerol that takes place in the endoplasmic reticulum. This second route may supplement this pathway. All membrane-localized enzymes are coloured dark green in the image. First, dihydroxyacetone phosphate (or glycerone phosphate) from glycolysis is used by the cytosolic enzyme glycerol-3-phosphate dehydrogenase [NAD(+)] to synthesize sn-glycerol 3-phosphate. Second, the mitochondrial outer membrane enzyme glycerol-3-phosphate acyltransferase esterifies an acyl-group to the sn-1 position of sn-glycerol 3-phosphate to form 1-acyl-sn-glycerol 3-phosphate (lysophosphatidic acid or LPA). Third, the enzyme 1-acyl-sn-glycerol-3-phosphate acyltransferase converts LPA into phosphatidic acid (PA or 1,2-diacyl-sn-glycerol 3-phosphate) by esterifying an acyl-group to the sn-2 position of the glycerol backbone. PA is then transferred to the inner mitochondrial membrane to continue cardiolipin synthesis. Fourth, magnesium-dependent phosphatidate cytidylyltransferase catalyzes the conversion of PA into CDP-diacylglycerol. Fifth, CDP-diacylglycerol--glycerol-3-phosphate 3-phosphatidyltransferase synthesizes phosphatidylglycerophosphate (PGP). Sixth, phosphatidylglycerophosphatase and protein-tyrosine phosphatase dephosphorylates PGP to form phosphatidylglycerol (PG). Last, cardiolipin synthase catalyzes the synthesis of cardiolipin by transferring a phosphatidyl group from a second CDP-diacylglycerol to PG. It requires a divalent metal cation cofactor.

D-Glucarate and D-Galactarate Degradation

Bacteroides sp. D22
Galactarate is a naturally occurring dicarboxylic acid analog of D-galactose. E. coli can use both diacid sugars galactarate and D-glucarate as the sole source of carbon for growth. The initial step in the degradation of galactarate is its dehydration to 5-dehydro-4-deoxy-D-glucarate(2--) by galactarate dehydratase. Glucaric acid can also be dehydrated by a glucarate dehydratase resulting in water and 5-dehydro-4-deoxy-D-glucarate(2--). The 5-dehydro-4-deoxy-D-glucarate(2--) is then metabolized by a alpha-dehydro-beta-deoxy-D-glucarate aldolase resulting in pyruvic acid and a tartonate semialdehyde. Pyruvic acid interacts with coenzyme A through a NAD driven Pyruvate dehydrogenase complex resulting in a carbon dioxide, an NADH and an acetyl-CoA. The tartronate semialdehyde interacts with a hydrogen ion through a NADPH driven tartronate semialdehyde reductase resulting in a NADP and a glyceric acid. The glyceric acid is phosphorylated by an ATP-driven glycerate kinase 2 resulting in an ADP, a hydrogen ion and a 2-phosphoglyceric acid. The latter compound is dehydrated by an enolase resulting in the release of water and a phosphoenolpyruvic acid. The phosphoenolpyruvic acid interacts with a hydrogen ion through an ADP driven pyruvate kinase resulting in an ATP and a pyruvic acid. The pyruvic acid then interacts with water and an ATP through a phosphoenolpyruvate synthetase resulting in the release of a hydrogen ion, a phosphate, an AMP and a Phosphoenolpyruvic acid.

Fatty Acid Elongation (Saturated)

Bacteroides sp. D22
The fatty acid elongation pathway shows an elongation cycle of an acyl-ACP chain by adding two carbons. Acetoacetyl-acp is produced from interaction of 3-oxoacyl-acp synthase 3 with malonyl-acp and Acetyl-CoA, and then Acetoacetyl-acp produce a 3-oxoacyl acp spontaneously. 3-oxoacyl acp will undergo the cycles of the elongation. The first step is converting the oxoacyl acp into a (3R) 3-hydroxyacyl(acp) through a 3-oxoacyl[acp] reductase.This second step converts the hydroxyacyl into a trans 2 enoyl acp through a protein complex conformed of a hydroxomyristoyl dehydratase and a hydroxydecanoyl dehydratase. The third step can be reached through two different reactions with a enoyl-acp reductase, involving NADPH or NADH. This leads to the production of a 2,3,4-saturated fatty acyl acp. For the final step the 2,3,4 fatty acyl acp is turned into a oxoacyl acp through a 3-oxoacyl acp synthase protein complex. The products of multiple of the elongation cycle are phospholipids, lipoproteins (saturated fatty acids), lauric and other fatty acid-containing compounds.

Glycine Biosynthesis

Bacteroides sp. D22
Glycine biosynthesis is dependent on L-serine. L-serine is enters the cell through transporters (serine / threonine:H+ symporter TdcC, serine/threonine: Na symporter , serine:H+ symporter SdaC) and then proceeds through reversible reaction with a tetrahydrofolic acid through a serine hydroxymethyltransferase enzyme in order to produce glycine, 5,10-methylene tetrahydrofolate and water. 5,10-methylene tetrahydrofolate is a major source of one-carbon units used in other metabolic pathways.
