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.
