In [[enzymology]], a '''ribose-5-phosphate adenylyltransferase''' ({{EC number|2.7.7.35}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]

:ADP + D-ribose 5-phosphate <math>\rightleftharpoons</math> phosphate + ADP-ribose

Thus, the two [[substrate (biochemistry)|substrates]] of this enzyme are [[adenosine diphosphate|ADP]] and [[D-ribose 5-phosphate]], whereas its two [[product (chemistry)|products]] are [[phosphate]] and [[ADP-ribose]].

This enzyme belongs to the family of [[transferase]]s, specifically those transferring phosphorus-containing [[nucleotide]] groups ([[nucleotidyltransferase]]s).  The systematic name of this enzyme class is '''ADP:D-ribose-5-phosphate adenylyltransferase'''. Other names in common use include '''ADP ribose phosphorylase''', and '''adenosine diphosphoribose phosphorylase'''.
