Inosine monophosphate

Inosine monophosphate (IMP) is an inosine nucleotide.

The enzyme hypoxanthine-guanine phosphoribosyltransferase converts hypoxanthine to IMP.

AMP can be converted into IMP by the enzyme myoadenylate deaminase, freeing an ammonia group.

The generation of IMP from R5P is the initial step in purine metabolism:
