Protein
S-adenosylmethionine synthase
Organism
Drosophila melanogaster
Function
Catalyzes the formation of S-adenosylmethionine from methionine and ATP. The reaction comprises two steps that are both catalyzed by the same enzyme: formation of S-adenosylmethionine (AdoMet) and triphosphate, and subsequent hydrolysis of the triphosphate.
Similarity
Belongs to the AdoMet synthase family.
