Gene

HCBG_05904

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.UniRule annotation

Catalytic activityi

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