CC   -!- FUNCTION: Putative steroid 6-beta-hydroxylase.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=an organic molecule + O2 + reduced [NADPH--hemoprotein
CC         reductase] = an alcohol + H(+) + H2O + oxidized [NADPH--hemoprotein
CC         reductase]; Xref=Rhea:RHEA:17149, Rhea:RHEA-COMP:11964, Rhea:RHEA-

CC         ChEBI:CHEBI:142491; EC=1.14.14.1;
CC   -!- COFACTOR:
CC       Name=heme; Xref=ChEBI:CHEBI:30413; Evidence={ECO:0000250};
CC   -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane {ECO:0000305};
CC       Peripheral membrane protein {ECO:0000305}. Microsome membrane
CC       {ECO:0000305}; Peripheral membrane protein {ECO:0000305}.
CC   -!- TISSUE SPECIFICITY: Highly expressed in liver and intestine. Moderate
CC       expression in gill and spleen. Low expression in kidney, brain and
CC       heart. {ECO:0000269|PubMed:12842592}.
CC   -!- SIMILARITY: Belongs to the cytochrome P450 family. {ECO:0000305}.
CC   -!- CAUTION: Due to a recent gene duplication event, CYP3A30 and CYP3A56
CC       are very similar. Because of this it was not possible to distinguish
CC       between the two genes when measuring the tissue expression.
CC       {ECO:0000305}.
