Inosine Monophosphate 304-328 adenine phosphoribosyltransferase Homo sapiens 25-29 31160323-5 2019 Here we present the crystal structures of hAPRT complexed to three cellular nucleotide analogs (hypoxanthine, IMP, and GMP) that we compare with the phosphate-bound enzyme. Inosine Monophosphate 110-113 adenine phosphoribosyltransferase Homo sapiens 42-47
