CC   -!- FUNCTION: Probable inactive heme oxygenase that may play a role in the
CC       regulation of phytochrome assembly and photomorphogenesis.
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Plastid, chloroplast.
CC   -!- SIMILARITY: Belongs to the heme oxygenase family. {ECO:0000305}.
CC   -!- CAUTION: Lacks the conserved His residue involved in heme iron binding
CC       and essential for heme oxygenase activity. Its enzyme activity is
CC       therefore unsure. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=AAK52555.1; Type=Erroneous gene model prediction; Evidence={ECO:0000305};
