MetaCyc Enzyme: p-ethylphenol methylhydroxylase

Species: Aromatoleum aromaticum EbN1

Subunit composition of p-ethylphenol methylhydroxylase = [PchC][PchF]
         p-ethylphenol methylhydroxylase subunit 1 = PchC
         p-ethylphenol methylhydroxylase subunit 2 = PchF

Summary:
The enzymes involved in the 1-ethyl-4-hydroxybenzene degradation pathway of Aromatoleum aromaticum EbN1 are encoded in a single large operon ( approximately 15 kb). They include a p-cresol methylhydroxylase-like protein (encoded by pchC and pchF), proposed to be a p-ethylphenol methylhydroxylase, two predicted alcohol dehydrogenases (encoded by chnA and ebA309), a biotin-dependent carboxylase (encoded by xccA, xccB and xccC), an acetoacetyl-CoA synthetase-like protein (acsA) and a thiolase (tioL).

None of these enzymes has been verified biochemically yet. However, expression of these proteins was shown to be upregulated in cells adapted to anaerobic growth with 1-ethyl-4-hydroxybenzene and 4-hydroxyacetophenone [Wohlbrand08].
