<p>This entry represents the enzyme (UbiB) which catalyses the first hydroxylation step in the ubiquinone biosynthetic pathway in bacteria [<cite idref="PUB00013848"/>, <cite idref="PUB00013772"/>]. The gene is also known as AarF in certain species. It is believed that the reaction converts 2-polyprenylphenol to 6-hydroxy-2-polyprenylphenol. Members are mainly proteobacteria.</p> Probable ubiquinone biosynthesis protein UbiB
