|Gene:||glyA||Accession Number: G-3267 (MetaCyc)|
Species: Methylobacterium extorquens AM1
The serine hydroxymethyltransferase from M. extorquens has not been purified, and little is known about it. The gene glyA was cloned, and mutants which were disruppted in this gene were created. The mutants failed to grow on methanol, methylamine, ethanol, and ethylamine. Introduction of a plasmid with the cloned gene into the mutants restored wild type phenotype. The subunit structure of the enzyme or the size of its components were not studied.
Molecular Weight of Polypeptide: 46.3 kD (from nucleotide sequence)

Enzymatic reaction of: serine hydroxymethyltransferase
EC Number: 126.96.36.199
The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the direction in which it was curated.
This reaction is reversible.
Serine hydroxymethyltransferase catalyzes the reversible conversion of serine to glycine and tetrahydrofolate to 5,10-methylene tetrahydrofolate.
