The subunit composition of the human NADH dehydrogenase obtained by rapid one-step immunopurification.
-
NDUFB3 is identified by mass spectrometry as a subunit of immunopurified human Complex I (NADH dehydrogenase).
"we can resolve and identify the human homologues of 42 polypeptides detected so far in the more extensively studied"
Accessory subunits are integral for assembly and function of human mitochondrial complex I.
-
Human Complex I comprises 45 subunits; 14 core subunits are shared with bacteria and are essential for enzymatic function, and 31 are accessory subunits.
"Bacterial and human complex I share 14 core subunits that are essential for enzymatic function"
-
25 of the accessory subunits are strictly required for assembly of a functional Complex I, and loss of a subunit destabilizes co-module subunits.
"We show that 25 subunits are strictly required for assembly of a functional complex"
Architecture of Human Mitochondrial Respiratory Megacomplex I(2)III(2)IV(2).
-
Cryo-EM of the human respiratory megacomplex reveals the precise assignment of individual Complex I subunits, providing the structural basis for NDUFB3 as an inner-membrane Complex I subunit.
"reveals the precise assignment of individual subunits of human CI"
Assembly of mammalian oxidative phosphorylation complexes I-V and supercomplexes.
-
OXPHOS complexes contain core catalytic proteins plus many supernumerary subunits with essential roles in assembly, regulation and stability; complexes I, III and IV form respiratory supercomplexes.
"a large number of 'supernumerary' subunits that play essential roles in assembly, regulation and stability."
Quantitative high-confidence human mitochondrial proteome and its dynamics in cellular context.
Identification and primary structure of five human NADH-ubiquinone oxidoreductase subunits.
-
Complex I is the first enzyme complex in the mitochondrial electron transport chain; NDUFB3 is one of its nuclear-encoded subunits.
"complex I) is the first enzyme complex in the electron transport chain of mitochondria"
cDNA of eight nuclear encoded subunits of NADH:ubiquinone oxidoreductase: human complex I cDNA characterization completed.
-
Complex I is an inner-membrane multiprotein complex whose main function is electron transport from NADH to ubiquinone coupled to proton translocation.
"Its main function is the transport of electrons from NADH to ubiquinone, which is accompanied by translocation of protons from the mitochondrial matrix to the intermembrane space."
Complex I oxidises NADH to NAD+, reduces CoQ to CoQH2
Intermediate 1 binds HP subcomplex to form Intermediate 2
Peripheral arm subunits bind the 815kDa complex to form a 980kDa complex
Intermediate 2 binds MT-ND1:NDUFAF5:NDUFAF6 to form a 315kDa subcomplex
The MCIA complex, NDUFAF2-7 all dissociate from the 980kDa complex, resulting in Complex I
ND4, ND5 bind the 550kDa complex to form the 815kDa complex
The 315kDa subcomplex binds the 370kDa subcomplex to form the 550kDa complex
