This chemical is often termed PGA when referring to the Calvin cycle. In the Calvin cycle, two glycerate 3-phosphate molecules are reduced to form two molecules of glyceraldehyde 3-phosphate (GALP).

L-malic acid is then metabolized through 3 possible ways: NAD driven malate dehydrogenase resulting in oxalacetic acid, NADP driven malate dehydrogenase B resulting pyruvic acid or malate dehydrogenase, NAD-requiring resulting in pyruvic acid. Oxalacetic acid is processed by phosphoenolpyruvate carboxykinase (ATP driven) while pyruvic acid is processed by phosphoenolpyruvate synthetase resulting in phosphoenolpyruvic acid. This compound is dehydrated by enolase resulting in an 2-phosphoglyceric acid. This compound is then isomerized by 2,3-bisphosphoglycerate-independent phosphoglycerate mutase resulting in a 3-phosphoglyceric acid which is phosphorylated by an ATP driven phosphoglycerate kinase resulting in an glyceric acid 1,3-biphosphate. This compound undergoes an NADH driven glyceraldehyde 3-phosphate dehydrogenase reaction resulting in a D-Glyceraldehyde 3-phosphate which is first isomerized into dihydroxyacetone phosphate through an triosephosphate isomerase. D-glyceraldehyde 3-phosphate and Dihydroxyacetone phosphate react through a fructose biphosphate aldolase protein complex resulting in a fructose 1,6-biphosphate. This compound is metabolized by a fructose-1,6-bisphosphatase resulting in a Beta-D-fructofuranose 6-phosphate which is then isomerized into a Beta-D-glucose 6-phosphate through a glucose-6-phosphate isomerase. PW000819 Metabolic Secondary Metabolites: cysteine biosynthesis from serine The pathway starts with a 3-phosphoglyceric acid interacting with an NAD driven D-3-phosphoglycerate dehydrogenase / α-ketoglutarate reductase resulting in an NADH, a hydrogen ion and a phosphohydroxypyruvic acid. This compound then interacts with an L-glutamic acid through a 3-phosphoserine aminotransferase / phosphohydroxythreonine aminotransferase resulting in a oxoglutaric acid and a DL-D-phosphoserine. The latter compound then interacts with a water molecule through a phosphoserine phosphatase resulting in a phosphate and an L-serine. The L-serine interacts with an acetyl-coa through a serine acetyltransferase resulting in a release of a Coenzyme A and a O-Acetylserine. The O-acetylserine then interacts with a hydrogen sulfide through a O-acetylserine sulfhydrylase A resulting in an acetic acid, a hydrogen ion and an L-cysteine PW000977 Metabolic cysteine biosynthesis The pathway of cysteine biosynthesis is a two-step conversion starting from L-serine and yielding L-cysteine. L-serine biosynthesis is shown for context. L-cysteine can also be synthesized from sulfate derivatives. The process through L-serine involves a serine acetyltransferase that produces a O-acetylserine which reacts together with hydrogen sulfide through a cysteine synthase complex in order to produce L-cysteine and acetic acid. Hydrogen sulfide is produced from a sulfate. Sulfate reacts with sulfate adenylyltransferase to produce adenosine phosphosulfate. This compound in turn is phosphorylated through a adenylyl-sulfate kinase into a phosphoadenosine phosphosulfate which in turn reacts with a phosphoadenosine phosphosulfate reductase to produce a sulfite. The sulfite reacts with a sulfite reductase to produce the hydrogen sulfide. This pathway is regulated at the genetic level in its second step, wtih both cysteine synthase isozymes being under the positive control of the cysteine-responsive transcription factor CysB. It is also subject to very strong feedback inhibition of its first step by the final pathway product, cysteine. Although two cysteine synthase isozymes exist, only cysteine synthase A (CysK) forms a complex with serine acetyltransferase. CysK is also the only one of the two cysteine synthases that is required for cell viability on cysteine-free medium. Both steps in this pathway are reversible. Based on genetic and proteomic data, it appears that the cysteine synthases may actually act as a sulfur scavenging system during sulfur starvation, stripping sulfur off of L-cysteine, generating any number of variant amino acids in the process.
