General annotation (Comments)

Function

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. HAMAP-Rule MF_03155

Catalytic activity

S-methyl-5'-thioadenosine + phosphate = adenine + S-methyl-5-thio-alpha-D-ribose 1-phosphate. HAMAP-Rule MF_03155

Pathway

Amino-acid biosynthesis; L-methionine biosynthesis via salvage pathway; S-methyl-5-thio-alpha-D-ribose 1-phosphate from S-methyl-5'-thioadenosine (phosphorylase route): step 1/1. HAMAP-Rule MF_03155

Subunit structure

Homotrimer By similarity. HAMAP-Rule MF_03155

Subcellular location

Cytoplasm By similarity. Nucleus By similarity HAMAP-Rule MF_03155.

Sequence similarities

Belongs to the PNP/MTAP phosphorylase family. MTAP subfamily.
