To investigate the electron transfer pathway from CPR to HO, we examined the reactions of heme and verdoheme, the second intermediate in the heme degradation, complexed with rat HO-1 (rHO-1) using a rat FMN-depleted CPR; the FMN-depleted CPR was prepared by dialyzing the CPR mutant, Y140A/Y178A, against 2 M KBr. Degradation of heme in complex with rHO-1 did not occur with FMN-depleted CPR, notwithstanding that the FMN-depleted CPR was able to associate with the heme-rHO-1 complex with a binding affinity comparable with that of the wild-type CPR. Thus, the first electron to reduce the ferric iron of heme complexed with rHO-1 must be transferred from FMN. In contrast, verdoheme was converted to the ferric biliverdin-iron chelate with FMN-depleted CPR, and this conversion was inhibited by ferricyanide, indicating that electrons are certainly required for conversion of verdoheme to a ferric biliverdin-iron chelate and that they can be supplied from the FMN-depleted CPR through a pathway not involving FMN, probably via FAD. This conclusion was supported by the observation that verdoheme dimethyl esters were accumulated in the reaction of the ferriprotoporphyrin IX dimethyl ester-rHO-1 complex with the wild-type CPR. Ferric biliverdin-iron chelate, generated with the FMN-depleted CPR, was converted to biliverdin by the addition of the wild-type CPR or desferrioxamine. Thus, the final electron for reducing ferric biliverdin-iron chelate to release ferrous iron and biliverdin is apparently provided by the FMN of CPR.","subitem_description_type":"Abstract"}]},"item_21_description_60":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Journal Article","subitem_description_type":"Other"}]},"item_21_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"American Society for Biochemistry and Molecular Biology"}]},"item_21_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1074/jbc.M606163200","subitem_relation_type_select":"DOI"}}]},"item_21_relation_14":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://www.jbc.org/content/281/42/31659.long"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.jbc.org/content/281/42/31659.long","subitem_relation_type_select":"URI"}}]},"item_21_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"American Society for Biochemistry and Molecular Biology"},{"subitem_rights":"This research was originally published in Journal of Biological Chemistry.
