General annotation (Comments)

Function

Catalyzes the reversible interconversion of serine and glycine with tetrahydrofolate serving as the one-carbon carrier. SHMT also catalyzes the folate-independent retroaldol cleavage of allothreonine and 3-phenylserine and the irreversible conversion of 5,10-methenyltetrahydrofolate to 5-formyltetrahydrofolate.

Catalytic activity

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

Cofactor

Pyridoxal phosphate.

Pathway

One-carbon metabolism; tetrahydrofolate interconversion. HAMAP MF_00051

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

Subunit structure

Homodimer.

Subcellular location

Cytoplasm HAMAP MF_00051.

Induction

By CsgD.

Sequence similarities

Belongs to the SHMT family.

Biophysicochemical properties

Kinetic parameters:

KM=7 µM for tetrahydrofolate (Ref.17)

KM=140 µM for serine (Ref.17)

KM=300 µM for serine (Ref.10)
