Identification
NameProtein APA1
Synonyms
  • 5',5'''-P-1,P-4-tetraphosphate phosphorylase
  • ATP adenylyltransferase
  • Diadenosine 5',5'''-P1,P4-tetraphosphate phosphorylase
  • AP,A phosphorylase
  • AP-4-A phosphorylase
  • ADP-sulfurylase
Gene NameAPA1
Enzyme Class
Biological Properties
General FunctionInvolved in ATP adenylyltransferase activity
Specific FunctionAp4A phosphorylase catabolizes Ap4N nucleotides (where N is A,C,G or U). Additionally this enzyme catalyzes the conversion of adenosine-5-phosphosulfate (AMPs) plus Pi to ADP plus sulfate, the exchange of NDP and phosphate and the synthesis of Ap4A from AMPs plus ATP
