2011年8月1日 · The NDH-1 complex of Escherichia coli (E. coli) has a minimal composition that consists of 14 subunits (two subunits are fused into one protein). Its structure provides the simplest model for understanding the molecular mechanism of complex I as the proton pumping NAD(P)H-quinone oxidoreductase in various organisms.

2021年12月8日 · We determined the structure of the chloroplast PSI–NDH supercomplex from barley (Hordeum vulgare) by cryo-electron microscopy (cryo-EM), revealing detailed structural features for elucidating the...

2016年4月29日 · Some plants and many microalgal species have lost plastidial ndh genes and a functional NDH-1 complex during evolution, and studies have suggested that a plastidial type II NADH dehydrogenase (NDH-2) complex substitutes for the electron transport activity of NDH-1.

2020年1月30日 · NDH-1L couples the electron transport from ferredoxin (Fd) to plastoquinone (PQ) and proton pumping from cytoplasm to the lumen that drives the ATP production. NDH-1L-dependent CEF increases...

2005年1月3日 · A functional Ndh subcomplex was purified by Ni 2+ affinity chromatography and its subunit composition analyzed by mass spectrometry. Five plastid encoded subunits (NDH-A, -H, -I, -J, and -K) were identified as well as three new subunits (NDH-M, -N, and -O) homologous to cyanobacterial and higher plant proteins.

2010年8月1日 · The plastid ndh genes encode components of the thylakoid Ndh complex which purportedly acts as an electron feeding valve to adjust the redox level of the cyclic photosynthetic electron transporters. During the process of evolution from endosymbiosis to modern chloroplast, most cyanobacterial genes were lost or transferred to nucleus.

The polypeptides encoded by the chloroplast ndh genes and some nuclear genes form the thylakoid NADH dehydrogenase (Ndh) complex, homologous to the mitochondrial complex I. Except for Charophyceae (algae related to higher plants) and a few ...

2020年7月3日 · Prvi prikazi hrvatskoga grba sačuvani su u kamenim ulomcima. Tako je najstariji kvadratičasti pleter iz 9. stoljeća na arkadi ciborija u Arheološkom muzeju u Zadru. Hrvatski grb ugrađen je i u zvonik crkve sv. Lucije u Jurandvoru na otoku Krku.
