ndhK — Zea mays

Summary

ZM00001EB361610 (symbol ndhK) on maize chromosome 8 encodes a protein with NADH_UQ_OxRdtase_20Kd_su and NADH_UbQ_OxRdtase-like_20kDa domains, and is associated with oxidoreductase activity acting on NAD(P)H with a quinone acceptor, quinone binding, ubiquinone reductase activity, 4Fe-4S cluster binding, iron binding, redox activity, metal binding, and Zn binding. This gene is associated with aerobic respiration, electron transport coupled proton transport, C4 photosynthesis, mitochondrial and plastid gene expression, complex I and III assembly, and mitochondrial biogenesis. It localizes to the respiratory chain complex I, chloroplast thylakoid membrane, mitochondria, and plasmalemma. Associations with agronomic traits include respiration rate, cytoplasmic male sterility, heterosis, germination rate, seed dormancy, cold tolerance, grain size, chlorophyll content, and salt tolerance. Studies of related genes in other species link the family to NADH:ubiquinone oxidoreductase activity and photochemical quenching.
