Comments [?]

case <OC:Saccharomyces>
Function Catalyzes the hydroxylation of 2-hexaprenyl-3-methyl-6-methoxy-1,4-benzoquinol (DMQH2) during ubiquinone biosynthesis. Has also a structural role in the COQ enzyme complex, stabilizing COQ3 and COQ4 polypeptides.
else case <OC:Metazoa>
Function Catalyzes the hydroxylation of 2-polyprenyl-3-methyl-6-methoxy-1,4-benzoquinol (DMQH2) during ubiquinone biosynthesis. Has also a structural role in the COQ enzyme complex, stabilizing other COQ polypeptides. Involved in lifespan determination in a ubiquinone-independent manner.
else
Function Catalyzes the hydroxylation of 2-polyprenyl-3-methyl-6-methoxy-1,4-benzoquinol (DMQH2) during ubiquinone biosynthesis. Has also a structural role in the COQ enzyme complex, stabilizing other COQ polypeptides.
end case
Catalytic activity RHEA:50908: a 6-methoxy-3-methyl-2-all-trans-polyprenyl-1,4-benzoquinol + AH2 + O2 = A + a 3-demethylubiquinol + H2O
EC 1.14.99.60
Cofactor Fe cation
Note: Binds 2 iron ions per subunit.
Pathway Cofactor biosynthesis; ubiquinone biosynthesis.
case <OC:Vertebrata>
Subunit Component of a multi-subunit COQ enzyme complex, composed of at least @gn(COQ3), @gn(COQ4), @gn(COQ5), @gn(COQ6), @gn(COQ7) and @gn(COQ9). Interacts with @gn(ADCK4) and @gn(COQ6). Interacts with @gn(COQ9).
else case <OC:Fungi>
Subunit Component of a multi-subunit COQ enzyme complex, composed of at least @gn(COQ3), @gn(COQ4), @gn(COQ5), @gn(COQ6), @gn(COQ7) and @gn(COQ9).
else
Subunit Component of a multi-subunit COQ enzyme complex.
end case
Subcellular location Mitochondrion inner membrane; Peripheral membrane protein; Matrix side.
case not <AnyFeature:TransitM>
Miscellaneous This protein may be expected to contain an N-terminal transit peptide but none has been predicted.
end case
Similarity Belongs to the COQ7 family.
