In [[enzymology]], a '''putrescine N-hydroxycinnamoyltransferase''' ({{EC number|2.3.1.138}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]
:caffeoyl-CoA + putrescine <math>\rightleftharpoons</math> CoA + N-caffeoylputrescine
Thus, the two [[substrate (biochemistry)|substrates]] of this enzyme are [[caffeoyl-CoA]] and [[putrescine]], whereas its two [[product (chemistry)|products]] are [[coenzyme A|CoA]] and [[N-caffeoylputrescine]].
This enzyme belongs to the family of [[transferase]]s, specifically those [[acyltransferase]]s transferring groups other than aminoacyl groups.  The [[List of enzymes|systematic name]] of this enzyme class is '''caffeoyl-CoA:putrescine N-(3,4-dihydroxycinnamoyl)transferase'''. Other names in common use include '''caffeoyl-CoA putrescine N-caffeoyl transferase''', '''PHT''', '''putrescine hydroxycinnamoyl transferase''', '''hydroxycinnamoyl-CoA:putrescine hydroxycinnamoyltransferase''', and '''putrescine hydroxycinnamoyltransferase'''.
