FIGURE 1

Non-phosphorylated (glycerate) and phosphorylated (phosphohydroxypyruvate) pathways of serine formation. Enzymes: 1, PGA phosphatase; 2, glycerate dehydrogenase; 3, serine: glyoxylate and serine: pyruvate aminotransferase; 4, PGA dehydrogenase; 5, phosphoserine: 2-oxogutarate aminotransferase; 6, phosphoserine phosphatase. 2-OG – 2-oxoglutarate. In all figures amino acids are depicted in blue, adenylates, phosphate, and pyridine nucleotides – in red.
