Comment Type Description
Biophysicochemical Properties Kinetic parameters: KM=1.59 uM for cytochrome c {ECO:0000269|PubMed:11485306}; KM=1.46 uM for NADPH {ECO:0000269|PubMed:11485306}; Note=The Vmax of the reaction is 721 pmol/min/pmol enzyme towards cytochrome c, and 662 pmol/min/pmol enzyme toward NADPH.;
Catalytic Activity NADPH + n oxidized hemoprotein = NADP(+) + n reduced hemoprotein. {ECO:0000269|PubMed:11485306, ECO:0000269|PubMed:9368374, ECO:0000269|PubMed:9468503}.
Cofactor Name=FAD; Xref=ChEBI:CHEBI:57692; Evidence={ECO:0000269|PubMed:9468503}; Note=Binds 1 FAD per monomer. {ECO:0000269|PubMed:9468503};
Cofactor Name=FMN; Xref=ChEBI:CHEBI:58210; Evidence={ECO:0000269|PubMed:9468503}; Note=Binds 1 FMN per monomer. {ECO:0000269|PubMed:9468503};
Disruption Phenotype Accumulates 20% of ergosterol of wild type. {ECO:0000269|PubMed:9468503}.
Function This enzyme is required for electron transfer from NADP to cytochrome P450 in microsomes. It can also provide electron transfer to heme oxygenase and cytochrome B5. Involved in ergosterol biosynthesis. Has NADPH-dependent ferrireductase activity on the plasma membrane. {ECO:0000269|PubMed:11485306, ECO:0000269|PubMed:1730736, ECO:0000269|PubMed:9368374, ECO:0000269|PubMed:9468503}.
Induction By galactose and on the plasma membrane by iron or copper deficiency. Repressed by glucose. {ECO:0000269|PubMed:9368374}.
Miscellaneous Present with 46600 molecules/cell in log phase SD medium. {ECO:0000269|PubMed:14562106}.
Ptm Phosphorylated by the cyclin-CDK PCL1-PHO85. {ECO:0000269|PubMed:15082539}.
Similarity Contains 1 FAD-binding FR-type domain. {ECO:0000255|PROSITE-ProRule:PRU00716}.
Similarity Contains 1 flavodoxin-like domain. {ECO:0000255|PROSITE-ProRule:PRU00088}.
Similarity In the C-terminal section; belongs to the flavoprotein pyridine nucleotide cytochrome reductase family. {ECO:0000305}.
Subcellular Location Endoplasmic reticulum membrane; Single-pass membrane protein. Mitochondrion outer membrane; Single-pass membrane protein. Cell membrane; Single-pass membrane protein. Microsome.
Subunit Interacts with PCL1. {ECO:0000269|PubMed:15082539, ECO:0000269|PubMed:16407065}.
