Galkina K, Zubareva V, Kashko N, Lapashina A, Markova O, Feniouk B, et al.
Front Microbiol
. 2022 Apr;
13:816622.
PMID: 35401495
In mitochondria, a small protein IF suppresses the hydrolytic activity of ATP synthase and presumably prevents excessive ATP hydrolysis under conditions of energy deprivation. In yeast , IF homologs are...

. 2022 Mar;
1863(5):148544.
PMID: 35331734
Proton-translocating FF ATP synthase (F-ATPase) couples ATP synthesis or hydrolysis to transmembrane proton transport in bacteria, chloroplasts, and mitochondria. The primary function of the mitochondrial FF is ATP synthesis driven...

Biochem Biophys Res Commun
. 2018 Dec;
509(1):102-107.
PMID: 30580998
The ATPase activity of H-FF-ATP synthase (FF) is down-regulated by several mechanisms. The most universal of them found in bacterial, chloroplast and mitochondrial enzymes is non-competitive inhibition by MgADP (ADP-inhibition)....

1860(3):181-188.
PMID: 30528692
ATPase activity of proton-translocating FF-ATP synthase (F-type ATPase or F-ATPase) is suppressed in the absence of protonmotive force by several regulatory mechanisms. The most conservative of these mechanisms found in...

PMID: 30292690
While deviations from the optimal phenotype are deleterious, increased variation can prevent population extinction under severe stresses. Cell division asymmetry is an important source of microbial phenotypic heterogeneity. A consecutive...

PMID: 27659264
Reactive oxygen species generated in mitochondria are an important factor contributing to mitochondrial and cellular dysfunction underlying many degenerative diseases, chronic pathologies and aging. The idea of delivering antioxidant molecules...

PMID: 21454506
The C-terminal two α-helices of the ε-subunit of thermophilic Bacillus F(o)F(1)-ATP synthase (TF(o)F(1)) adopt two conformations: an extended long arm ("up-state") and a retracted hairpin ("down-state"). As ATP becomes poor,...

Saita E, Iino R, Suzuki T, Feniouk B, Kinosita Jr K, Yoshida M
J Biol Chem
. 2010 Feb;
285(15):11411-7.
PMID: 20154086
F(1)-ATPase (F(1)), a soluble portion of F(o)F(1)-ATP synthase (F(o)F(1)), is an ATP-driven motor in which gammaepsilon subunits rotate in the alpha(3)beta(3) cylinder. Activity of F(1) and F(o)F(1) from Bacillus PS3...

PMID: 20141757
Subunit epsilon of bacterial and chloroplast F(O)F(1)-ATP synthase is responsible for inhibition of ATPase activity. In Bacillus PS3 enzyme, subunit epsilon can adopt two conformations. In the "extended", inhibitory conformation,...

. 2007 Dec;
104(52):20776-81.
PMID: 18083842
Bacterial operons for F(1)F(o)-ATP synthase typically include an uncI gene that encodes a function-unknown small hydrophobic protein. When we expressed a hybrid F(1)F(o) (F(1) from thermophilic Bacillus PS3 and Na(+)-translocating...
