In enzymology a ribose-5-phosphate adenylyltransferase (EC 2.7.7.35) is an enzyme that catalyzes the chemical reactionADP + D-ribose 5-phosphate phosphate + ADP-riboseThus the two substrates of this enzyme are ADP and D-ribose 5-phosphate whereas its two products are phosphate and ADP-ribose.This enzyme belongs to the family of transferases specifically those transferring phosphorus-containing nucleotide groups (nucleotidyltransferases).
