Abstract Secretory lysosomes are required for the specialised functions of various types of differentiated cells. In osteoclasts, the lysosomal proton pump V-ATPase (vacuolar-type ATPase) is targeted to the plasma membrane via secretory lysosomes and

Vacuolar-type ATPase (V-ATPase), initially identified in yeast and plant vacuoles, pumps protons into the lumen of organelles coupled with ATP hydrolysis. The mammalian counterpart is found ubiquitously in endomembrane organelles and the plasma membr

The F1 sector of ATP synthase (FOF1) synthesizes or hydrolyses ATP via a rotational catalysis mechanism that couples chemical reaction with subunit rotation. Phytopolyphenols such as curcumin can inhibit bulk phase F1 ATPase activity by extending the

The γ subunit located at the center of ATP synthase (FOF1) plays critical roles in catalysis. Escherichia coli mutant with Pro substitution of the γ subunit residue γLeu218, which are located the rotor shaft near the c subunit ring, decreased NADH

Porphyromonas gingivalis is a well-known Gram-negative bacterium that causes periodontal disease. The bacterium metabolizes amino acids and peptides to obtain energy. An ion gradient across its plasma membrane is thought to be essential for nutrient

Protons (H) play vital roles in bioenergetics and ion homeostasis, as evidenced by the presence of unique acidic compartments both inside and outside of cells. The acidification of compartments results in an electrochemical proton gradient being gene

Escherichia coli ATP synthase (F0F1) couples catalysis and proton transport through subunit rotation. The ϵ subunit, an endogenous inhibitor, lowers F1-ATPase activity by decreasing the rotation speed and extending the duration of the inhibited stat

ATP synthase (F-ATPase) function depends upon catalytic and rotation cycles of the F1 sector. Previously, we found that F1 ATPase activity is inhibited by the dietary polyphenols, curcumin, quercetin, and piceatannol, but that the inhibitory kinetics

Curcumin, a dietary phytopolyphenol isolated from a perennial herb (Curcuma longa), is a well-known compound effective for bacterial infections and tumors, and also as an antioxidant. In this study, we report the inhibitory effects of curcumin and it
