CC   -!- FUNCTION: Involved in the metabolism of compounds associated with the
CC       development of flavor in the ripening fruit process, possibly by acting
CC       as trans-cinnamic acid 4-hydrolase.
CC   -!- COFACTOR:
CC       Name=heme; Xref=ChEBI:CHEBI:30413; Evidence={ECO:0000250};
CC   -!- SUBCELLULAR LOCATION: Microsome membrane; Single-pass membrane protein.
CC       Endoplasmic reticulum membrane; Single-pass membrane protein.
CC   -!- TISSUE SPECIFICITY: Mesocarp.
CC   -!- DEVELOPMENTAL STAGE: In ripening fruit.
CC   -!- INDUCTION: By ethylene.
CC   -!- SIMILARITY: Belongs to the cytochrome P450 family. {ECO:0000305}.
