Subunits

Subunits Comment Organism
More subunit NdhP is essential for stable NDH-1L assembly in Thermosynechococcus elongatus. It is localized in the NDH-1L specific distal unit of the NDH-1 complex, that is formed by the subunits NdhD1 and NdhF1 Thermosynechococcus vestitus

General Information

General Information Comment Organism
evolution the cyanobacterial NADPH:plastoquinone oxidoreductase complex (NDH-1) is related to Complex I of eubacteria and mitochondria. At least four different NDH-1 subtypes (NDH-1L, NDH-1L', NDH-1MS, NDH-1MS') have been identified or postulated for cyanobacteria so far. NDH-1L and NDH-1L' are involved in respiration whereas NDH1-MS and NDH-1MS' link the Complex I specific and electron flow dependent proton-pumping activity to unique carbon concentration mechanisms (CCM) in an undefined process. Electron transfer via ferredoxin might be a possible pathway to chloroplast NDH and cyanobacterial NDH-1 Thermosynechococcus vestitus
malfunction NdhP is essential for NDH-1L formation, as this type of NDH-1 is not detectable in a DndhP::Km mutant Thermosynechococcus vestitus
additional information NdhP is a unique component of the 450 kDa NDH-1L complex, that is involved in respiration and CET at high CO2 concentration, and not detectable in the NDH-1MS and NDH-1MS' complexes that play a role in carbon concentration Thermosynechococcus vestitus
physiological function the cyanobacterial NADPH:plastoquinone oxidoreductase complex (NDH-1) is related to Complex I of eubacteria and mitochondria, it plays a pivotal role in respiration as well as in cyclic electron transfer (CET) around PSI and is involved in a unique carbon concentration mechanism (CCM). NdhP peptide is a unique component of the NDH-1L subtype and essential for its assembly. Electron transfer via ferredoxin might be a possible pathway to chloroplast NDH and cyanobacterial NDH-1 Thermosynechococcus vestitus
