Predicted to enable phosphoribosylformylglycinamidine synthase activity. Involved in glutamine metabolic process; response to xenobiotic stimulus; and ribonucleoside monophosphate biosynthetic process. Biomarker of hepatocellular carcinoma. Orthologous to human PFAS (phosphoribosylformylglycinamidine synthase). [provided by Alliance of Genome Resources, Apr 2022]
