Protein

S-adenosylmethionine synthase

Gene

metK

Organism
Helicobacter acinonychis (strain Sheeba)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

Catalyzes the formation of S-adenosylmethionine from methionine and ATP. The overall synthetic reaction is composed of two sequential steps, AdoMet formation and the subsequent tripolyphosphate hydrolysis which occurs prior to release of AdoMet from the enzyme.UniRule annotation

Catalytic activityi

ATP + L-methionine + H2O = phosphate + diphosphate + S-adenosyl-L-methionine.UniRule annotation

Cofactori

Binds 2 divalent ions per subunit. Magnesium or cobalt.UniRule annotation
Binds 1 potassium ion per subunit.UniRule annotation
