2.4.2.44 |
Accepted name: |
S-methyl-5′-thioinosine phosphorylase |
Reaction: |
S-methyl-5′-thioinosine + phosphate = hypoxanthine + S-methyl-5-thio-α-D-ribose 1-phosphate |
Other name(s): |
MTIP; MTI phosphorylase; methylthioinosine phosphorylase |
Systematic name: |
S-methyl-5′-thioinosine:phosphate S-methyl-5-thio-α-D-ribosyl-transferase |
Comments: |
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, S-methyl-5′-thioadenosine deaminase) and phosphorolysis to hypoxanthine [1]. |
