Protein Name:
Bifunctional purine biosynthesis protein ATIC
|
UniprotKB/SwissProt ID: Q9VC18 (Q9VC18)
Gene Name:
BEST:GH11240
Organism: Drosophila melanogaster (Fruit fly)
Function: Bifunctional enzyme that catalyzes the last two steps of purine biosynthesis. Acts as a transformylase that incorporates a formyl group to the AMP analog AICAR (5-amino-1-(5-phospho-beta-D-ribosyl)imidazole-4-carboxamide) to produce the intermediate formyl-AICAR (FAICAR). Can use both 10-formyldihydrofolate and 10-formyltetrahydrofolate as the formyl donor in this reaction. Also catalyzes the cyclization of FAICAR to inosine monophosphate (IMP). Promotes insulin receptor/INSR autophosphorylation and is involved in INSR internalization
