== Function ==
[https://www.uniprot.org/uniprot/IMDH_TRIFO IMDH_TRIFO] 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. Could also have a single-stranded nucleic acid-binding activity and could play a role in RNA and/or DNA metabolism.<ref>PMID:10029522</ref>
