IntEnz Enzyme Nomenclature
EC 4.1.1.83

Names

Accepted name:
4-hydroxyphenylacetate decarboxylase
Other names:
p-hydroxyphenylacetate decarboxylase
p-Hpd
4-Hpd
4-hydroxyphenylacetate carboxy-lyase
Systematic name:
4-(hydroxyphenyl)acetate carboxy-lyase (4-methylphenol-forming)

Reaction

Comments:

The enzyme, from the strict anaerobe Clostridium difficile, can also use (3,4-dihydroxyphenyl)acetate as a substrate, yielding 4-methylcatechol as a product. The enzyme is a glycyl radical enzyme.
