Keyword - Ubiquinone biosynthesis (KW-0831)


Protein involved in the synthesis of ubiquinone which involves the conversion of chorismate into 4-hydroxy-benzoate, to which is added six to ten isoprene units to form polyprenyl phenol. The addition of a further oxygen atom at C3, followed by the transfer of three methyl groups from S-adenosine methionine gives rise to ubiquinol, which is further reduced to ubiquinone (6-polyprenyl-2,3-dimethoxy-5-methyl-1,4-benzoquinone).
