Protein
S-methyl-5'-thioadenosine phosphorylase
Gene
mtnP, blr0960
Organism
Bradyrhizobium diazoefficiens (strain JCM 10833 / IAM 13628 / NBRC 14792 / USDA 110)
Status
Reviewed - Annotation score: 3 out of 5 - Protein inferred from homologyi

Functioni

Catalyzes the reversible phosphorylation of S-methyl-5'-thioadenosine (MTA) to adenine and 5-methylthioribose-1-phosphate. Involved in the breakdown of MTA, a major by-product of polyamine biosynthesis. Responsible for the first step in the methionine salvage pathway after MTA has been generated from S-adenosylmethionine. Has broad substrate specificity with 6-aminopurine nucleosides as preferred substrates By similarity.UniRule annotation

Catalytic activityi

S-methyl-5'-thioadenosine + phosphate = adenine + S-methyl-5-thio-alpha-D-ribose 1-phosphate.UniRule annotation
