Crystal Structure of the Catalytic Domain of the Inosine Monophosphate Dehydrogenase from Cryptosporidium parvum

Template:ABSTRACT PUBMED 23668331

Function

[IMDH_CRYPV] Catalyzes the conversion of inosine 5'-phosphate (IMP) to xanthosine 5'-phosphate (XMP), the first committed and rate-limiting step in the de novo synthesis of guanine nucleotides, and therefore plays an important role in the regulation of cell growth (By similarity).^[1]
