CommentThis model represents the enzyme (UbiB) which catalyzes the first hydroxylation step in the ubiquinone biosynthetic pathway in bacteria [1,2]. It is believed that the reaction is 2-polyprenylphenol -> 6-hydroxy-2-polyprenylphenol. This model finds hits primarily in the proteobacteria. The gene is also known as AarF in certain species.
