| Primary Identifier | IPR006371 | Type | Family |
| Short Name | HB_polyprenyl-transferase-rel |
| description | A fairly deep split separates this polyprenyltransferase subfamily from the set of mitochondrial and proteobacterial 4-hydroxybenzoate polyprenyltransferases, described in . Protoheme IX farnesyltransferase (heme O synthase) () is more distantly related. Because no species appears to have both this protein and a member of , it is likely that this family of sequences represent 4-hydroxybenzoate polyprenyltransferase, a critical enzyme of ubiquinone biosynthesis, in the Archaea, Gram-positive bacteria, Aquifex aeolicus, and the Chlamydias. |
