Enzyme Information

1.14.13.240

2-polyprenylphenol 6-hydroxylase.

based on mapping to UniProt P25535

2-(all-trans-polyprenyl)phenol + NADPH + O(2) = 3-(all-trans- polyprenyl)benzene-1,2-diol + NADP(+) + H(2)O.

-!- The enzyme from the bacterium Escherichia coli (UbiI) catalyzes the first hydroxylation during the aerobic biosynthesis of ubiquinone. -!- The enzyme from the bacterium Neisseria meningitidis (UbiM) can also catalyze the two additional hydroxylations that occur in the pathway (cf. EC 1.14.99.60).
