Identification
NameAdenine phosphoribosyltransferase 2
Synonyms
  • APRT 2
Gene NameAPT2
Enzyme Class
Biological Properties
General FunctionInvolved in adenine phosphoribosyltransferase activity
Specific FunctionCatalyzes a salvage reaction resulting in the formation of AMP, that is energically less costly than de novo synthesis. May lack catalytic activity
