ENZYME entry: EC 1.14.15.25

Accepted Name
p-cymene methyl-monooxygenase.
Alternative Name(s)
p-cymene methyl hydroxylase.
Reaction catalysed
p-cymene + O(2) + 2 reduced ferredoxin [iron-sulfur] cluster + 2 H(+) <=> 4-isopropylbenzyl alcohol + 2 oxidized ferredoxin [iron-sulfur] cluster + H(2)O
Comment(s)
  • The enzyme, characterized from several Pseudomonas strains, initiates p-cymene catabolism through hydroxylation of the methyl group.
  • The enzyme has a distinct preference for substrates containing at least an alkyl or heteroatom substituent at the para-position of toluene.
  • The electrons are provided by a reductase (EC 1.18.1.3) that transfers electrons from NADH via FAD and an [2Fe-2S] cluster.
  • In Pseudomonas chlororaphis the presence of a third component of unknown function greatly increases the activity.
  • Cf. EC 1.14.15.26.
