CC -!- FUNCTION: Catalyzes the hydroxylation of 2-polyprenyl-3-methyl-6-
CC methoxy-1,4-benzoquinol (DMQH2) during ubiquinone biosynthesis. Has
CC also a structural role in the COQ enzyme complex, stabilizing other COQ
CC polypeptides (By similarity). Involved in lifespan determination in a
CC ubiquinone-independent manner (PubMed:19478076). Plays a role in
CC modulating mitochondrial stress responses, acting in the nucleus,
CC perhaps via regulating gene expression, independent of its
CC characterized mitochondrial function in ubiquinone biosynthesis.
CC {ECO:0000250|UniProtKB:Q99807, ECO:0000255|HAMAP-Rule:MF_03194,
CC ECO:0000269|PubMed:19478076}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a 6-methoxy-3-methyl-2-all-trans-polyprenyl-1,4-benzoquinol +
CC AH2 + O2 = A + a 3-demethylubiquinol + H2O; Xref=Rhea:RHEA:50908,

CC Evidence={ECO:0000255|HAMAP-Rule:MF_03194};
CC -!- COFACTOR:
CC Name=Fe cation; Xref=ChEBI:CHEBI:24875;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_03194};
CC Note=Binds 2 iron ions per subunit. {ECO:0000255|HAMAP-Rule:MF_03194};
CC -!- PATHWAY: Cofactor biosynthesis; ubiquinone biosynthesis.
CC {ECO:0000255|HAMAP-Rule:MF_03194}.
CC -!- SUBUNIT: Component of a multi-subunit COQ enzyme complex, composed of
CC at least COQ3, COQ4, COQ5, COQ6, COQ7 and COQ9. Interacts with COQ8B
CC and COQ6. Interacts with COQ9. {ECO:0000255|HAMAP-Rule:MF_03194}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion inner membrane {ECO:0000255|HAMAP-
CC Rule:MF_03194, ECO:0000269|PubMed:11387338}; Peripheral membrane
CC protein {ECO:0000255|HAMAP-Rule:MF_03194, ECO:0000269|PubMed:11387338};
CC Matrix side {ECO:0000255|HAMAP-Rule:MF_03194,
CC ECO:0000269|PubMed:11387338}.
CC -!- TISSUE SPECIFICITY: Highly expressed in tissues with high energy demand
CC such as heart, muscle, liver, and kidney.
CC {ECO:0000269|PubMed:11511092}.
CC -!- DISRUPTION PHENOTYPE: Mice lacking Coq7 start to die after E8.
CC Heterozygous mutant reveal that the reduction of Coq7 levels in these
CC animals profoundly alters their mitochondrial function despite the fact
CC that ubiquinone production is unaffected. The mitochondria of young
CC mutants heterozygous are dysfunctional, exhibiting reduced energy
CC metabolism and a substantial increase in oxidative stress.
CC {ECO:0000269|PubMed:19478076}.
CC -!- MISCELLANEOUS: In life-span analysis, transgenic expression reverted
CC the extended life span of clk-1 to the comparable level with wild-type
CC control.
CC -!- SIMILARITY: Belongs to the COQ7 family. {ECO:0000255|HAMAP-
CC Rule:MF_03194}.
