In [[enzymology]], a '''dolichyl-diphosphate-polyphosphate phosphotransferase''' ({{EC number|2.7.4.20}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]

:dolichyl diphosphate + (phosphate)n <math>\rightleftharpoons</math> dolichyl phosphate + (phosphate)n<sup>+</sup>1

Thus, the two [[substrate (biochemistry)|substrates]] of this enzyme are [[dolichyl diphosphate]] and [[(phosphate)n]], whereas its two [[product (chemistry)|products]] are [[dolichyl phosphate]] and [[(phosphate)n+1]].

This enzyme belongs to the family of [[transferase]]s, specifically those transferring phosphorus-containing groups ([[phosphotransferase]]s) with a phosphate group as acceptor.  The systematic name of this enzyme class is '''dolichyl-diphosphate:polyphosphate phosphotransferase'''. This enzyme is also called '''dolichylpyrophosphate:polyphosphate phosphotransferase'''.
