Protein
S-adenosylmethionine synthase
Gene
metK, CBU_2030
Organism
Coxiella burnetii (strain RSA 493 / Nine Mile phase I)
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 By similarity.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 By similarity.
Binds 1 potassium ion per subunit By similarity.UniRule annotation
