    Serine hydroxymethyltransferase (SHMT) is a ubiquitous enzyme found in all prokaryotes and eukaryotes. As an enzyme of the thymidylate synthase metabolic cycle, SHMT catalyses the retro-aldol cleavage of serine to glycine, with the resulting hydroxymethyl group being transferred to tetrahydrofolate to form 5, 10-methylene-tetrahydrofolate. The latter is the major source of one-carbon units in metabolism. Elevated SHMT activity has been shown to be coupled to the increased demand for DNA synthesis in rapidly proliferating cells, particularly tumour cells. Consequently, the central role of SHMT in nucleotide biosynthesis makes it an attractive target for cancer chemotherapy.
