General annotation (Comments)

Function

Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate (THF) serving as the one-carbon carrier. This reaction serves as the major source of one-carbon groups required for the biosynthesis of purines, thymidylate, methionine, and other important biomolecules. Also exhibits THF-independent aldolase activity toward beta-hydroxyamino acids, producing glycine and aldehydes, via a retro-aldol mechanism By similarity. HAMAP-Rule MF_00051

Catalytic activity

5,10-methylenetetrahydrofolate + glycine + H2O = tetrahydrofolate + L-serine. HAMAP-Rule MF_00051

Cofactor

Pyridoxal phosphate By similarity. HAMAP-Rule MF_00051

Pathway

One-carbon metabolism; tetrahydrofolate interconversion. HAMAP-Rule MF_00051

Amino-acid biosynthesis; glycine biosynthesis; glycine from L-serine: step 1/1. HAMAP-Rule MF_00051

Subunit structure

Homodimer By similarity. HAMAP-Rule MF_00051

Subcellular location

Cytoplasm By similarity HAMAP-Rule MF_00051.

Sequence similarities

Belongs to the SHMT family.
