D-Glucarate and D-Galactarate Degradation

Helicobacter cinaedi CCUG 18818 = ATCC BAA-847
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.

Cardiolipin Biosynthesis CL(18:2(9Z,11Z)/16:1(9Z)/18:2(9Z,12Z)/18:2(9Z,12Z))

Mus musculus
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.

Glycine Biosynthesis

Helicobacter bilis ATCC 43879
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.

Serine Biosynthesis and Metabolism

Succinatimonas hippei YIT 12066
Serine biosynthesis is a major metabolic pathway in E. coli. Its end product, serine, is not only used in protein synthesis, but also as a precursor for the biosynthesis of glycine, cysteine, tryptophan, and phospholipids. In addition, it directly or indirectly serves as a source of one-carbon units for the biosynthesis of various compounds. The biosynthesis of serine starts with 3-phosphoglyceric acid being metabolized by a NAD driven D-3-phosphoglycerate dehydrogenase / α-ketoglutarate reductase resulting in the release of a NADH, a hydrogen ion and a phosphohydroxypyruvic acid. The latter compound then interacts with an L-glutamic acid through a 3-phosphoserine aminotransferase / phosphohydroxythreonine aminotransferase resulting in oxoglutaric acid and DL-D-phosphoserine. The DL-D-phosphoserine can also be imported into the cytoplasm through a phosphonate ABC transporter. The DL-D-phosphoserine is dephosphorylated by interacting with a water molecule through a phosphoserine phosphatase resulting in the release of a phosphate and an L-serine L-serine is then metabolized by being dehydrated through either a L-serine dehydratase 2 or a L-serine dehydratase 1 resulting in the release of a water molecule, a hydrogen ion and a 2-aminoacrylic acid. The latter compound is an isomer of a 2-iminopropanoate which reacts spontaneously with a water molecule and a hydrogen ion resulting in the release of Ammonium and pyruvic acid. Pyruvic acid then interacts with a coenzyme A through a NAD driven pyruvate dehydrogenase complex resulting in the release of a NADH, a carbon dioxide and an acetyl-CoA.

Tyrosine Biosynthesis

Tyrosine is one of the amino acid used in protein synthesis. The tyrosine biosynthesis pathways is connected with the chorismate biosynthesis pathway. Chorismate biosynthesis produce the chorismate, which can further be converted to prephenate by T-protein. Combined with cofactor, NAD, prephenate has been further converted to 4-Hydroxyphenylpyruvic acid by T-protein with generated NADH and carbon dioxide. Tyrosine aminotransferase catalyzes 4-Hydroxyphenylpyruvic acid to tyrosine, and also converts glutamic acid to oxoglutaric acid. Tyrosine will be further catalyzed into various molecules such as 2-iminoacetate, p-Cresol, 5'Deoxyadenosine and L-Methionine; or it will be exported from cell via the lysine exporter.
