Accepted name:
ADP ribose phosphorylase
Other names:
ribose-5-phosphate adenylyltransferase [ambiguous]
adenosine diphosphoribose phosphorylase [ambiguous]
ADP-ribose phosphorylase
Systematic name:
ADP:D-ribose-5-phosphate adenylyltransferase



The enzyme, characterized from the single-celled alga Euglena gracilis, catalyses an irreversible reaction in the direction of ADP formation. cf. EC, ADP-D-ribose pyrophosphorylase.
