complex I

General Information (Source: NCBI Gene,UniProt)

Text mining Term	complex I
UniProt ID	NU5C_HELAN
Name	NADH-plastoquinone oxidoreductase subunit 5 NAD(P)H-quinone oxidoreductase subunit 5, chloroplastic NAD(P)H dehydrogenase subunit 5
Gene Names	ndhF
Taxonomy	Helianthus annuus

General annotation

Function	NDH shuttles electrons from NAD(P)H:plastoquinone, via FMN and iron-sulfur (Fe-S) centers, to quinones in the photosynthetic chain and possibly in a chloroplast respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be plastoquinone. Couples the redox reaction to proton translocation, and thus conserves the redox energy in a proton gradient (By similarity).
Subcellular location	Plastid, chloroplast thylakoid membrane; Multi-pass membrane protein (By similarity).
