Alternate name: hypoxanthine-guanine phosphoribosyltransferase. Sequence differences as small as a single residue can affect whether members of this family act on hypoxanthine and guanine or hypoxanthine only. The designation of this model as equivalog reflects hypoxanthine specificity and does not reflect whether or not guanine can replace hypoxanthine.
