CC   -!- FUNCTION: Catalyzes the reversible phosphorylation of S-methyl-5'-
CC       thioadenosine (MTA) to adenine and 5-methylthioribose-1-phosphate.
CC       Involved in the breakdown of MTA, a major by-product of polyamine
CC       biosynthesis. Responsible for the first step in the methionine salvage
CC       pathway after MTA has been generated from S-adenosylmethionine. Has
CC       broad substrate specificity with 6-aminopurine nucleosides as preferred
CC       substrates. {ECO:0000255|HAMAP-Rule:MF_03155}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=phosphate + S-methyl-5'-thioadenosine = adenine + S-methyl-5-
CC         thio-alpha-D-ribose 1-phosphate; Xref=Rhea:RHEA:11852,
CC         ChEBI:CHEBI:16708, ChEBI:CHEBI:17509, ChEBI:CHEBI:43474,
CC         ChEBI:CHEBI:58533; EC=2.4.2.28; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_03155};
CC   -!- PATHWAY: Amino-acid biosynthesis; L-methionine biosynthesis via salvage
CC       pathway; S-methyl-5-thio-alpha-D-ribose 1-phosphate from S-methyl-5'-
CC       thioadenosine (phosphorylase route): step 1/1. {ECO:0000255|HAMAP-
CC       Rule:MF_03155}.
CC   -!- SUBUNIT: Homotrimer. {ECO:0000255|HAMAP-Rule:MF_03155}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_03155}.
CC       Nucleus {ECO:0000255|HAMAP-Rule:MF_03155}.
CC   -!- SIMILARITY: Belongs to the PNP/MTAP phosphorylase family. MTAP
CC       subfamily. {ECO:0000255|HAMAP-Rule:MF_03155}.
