In [[enzymology]], a '''4-hydroxyphenylpyruvate decarboxylase''' ({{EC number|4.1.1.80}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]

:4-hydroxyphenylpyruvate <math>\rightleftharpoons</math> 4-hydroxyphenylacetaldehyde + CO<sub>2</sub>

Hence, this enzyme has one [[substrate (biochemistry)|substrate]], [[4-hydroxyphenylpyruvate]], and two [[product (chemistry)|products]], [[4-hydroxyphenylacetaldehyde]] and [[carbon dioxide|CO<sub>2</sub>]].

This enzyme belongs to the family of [[lyase]]s, specifically the carboxy-lyases, which cleave carbon-carbon bonds.  The systematic name of this enzyme class is '''4-hydroxyphenylpyruvate carboxy-lyase (4-hydroxyphenylacetaldehyde-forming)'''. This enzyme is also called '''4-hydroxyphenylpyruvate carboxy-lyase'''.
