ENZYME entry: EC 2.4.2.44

Accepted Name
S-methyl-5'-thioinosine phosphorylase
Alternative Name(s)
methylthioinosine phosphorylase
MTI phosphorylase
Reaction catalysed
phosphate + S-methyl-5'-thioinosine <=> hypoxanthine + S-methyl-5-thio-alpha-D-ribose 1-phosphate
Comment(s)
  • No activity with S-methyl-5'-thioadenosine.
  • The catabolism of of 5'-methylthioadenosine in Pseudomonas aeruginosa involves deamination to S-methyl-5'-thioinosine (EC 3.5.4.31) and phosphorolysis to hypoxanthine.
