In [[enzymology]], a '''ribose isomerase''' ({{EC number|5.3.1.20}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]

:D-ribose <math>\rightleftharpoons</math> D-ribulose

Hence, this enzyme has one [[substrate (biochemistry)|substrate]], [[D-ribose]], and one [[product (chemistry)|product]], [[D-ribulose]].

This enzyme belongs to the family of [[isomerase]]s, specifically those intramolecular [[oxidoreductase]]s interconverting [[aldose]]s and [[ketose]]s.  The systematic name of this enzyme class is '''D-ribose aldose-ketose-isomerase'''. Other names in common use include '''D-ribose isomerase''', and '''D-ribose ketol-isomerase'''.
