Protein

S-methyl-5'-thioadenosine phosphorylase

Gene

FG08458.1

Organism
Gibberella zeae (strain PH-1 / ATCC MYA-4620 / FGSC 9075 / NRRL 31084) (Wheat head blight fungus) (Fusarium graminearum)
Status
Unreviewed-Annotation score: -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.UniRule annotation

Catalytic activityi

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

Pathwayi: L-methionine biosynthesis via salvage pathway

This protein is involved in step 1 of the subpathway that synthesizes S-methyl-5-thio-alpha-D-ribose 1-phosphate from S-methyl-5'-thioadenosine (phosphorylase route).UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. S-methyl-5'-thioadenosine phosphorylase (FG08458.1)
This subpathway is part of the pathway L-methionine biosynthesis via salvage pathway, which is itself part of Amino-acid biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes S-methyl-5-thio-alpha-D-ribose 1-phosphate from S-methyl-5'-thioadenosine (phosphorylase route), the pathway L-methionine biosynthesis via salvage pathway and in Amino-acid biosynthesis.
