G protein

General Information (Source: NCBI Gene,UniProt)

Text mining Term G protein
UniProt ID NDHK_CAPBU
Name NAD(P)H dehydrogenase subunit K
NAD(P)H-quinone oxidoreductase subunit K, chloroplastic
NADH-plastoquinone oxidoreductase subunit K
Gene Names ndhK
Taxonomy Capsella bursa-pastoris

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; Peripheral membrane protein; Stromal side (By similarity).
