1904 Jrnl. Chem. Soc. 86 i. 838 Fresh pancreas, when subjected to autolysis, does not yield adenine or guanine, and guanine which is added is transformed into xanthine within 3 days. The enzyme present in pancreas which induces this change is termed Guanase.
1967 Biochem. Jrnl. 104 634/1 Guanase (guanine aminohydrolase, EC 3.5.4.3) was of special interest as guanine is metabolically a precursor of xanthine and is thus indirectly a source of uric acid.
