Impact of an electric field on P-type ATPases [PDF]

, 2008
P-type ATPases are membrane proteins acting as ion pumps that drive an active transport of cations across the membrane against a concentration gradient. The required energy for the ion transport is provided by binding and hydrolysis of ATP.

The role of the host—Neutrophil biology

Periodontology 2000, EarlyView., 2023
Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...

Proton translocation induced by ATPase activity in chloroplasts [PDF]

FEBS Letters, 1970
Proton uptake by chloroplasts was induced by light‐triggered ATPase activity. A quotient of two was obtained when the initial rate of proton uptake was divided by the rate of Pi released from ATP. Gramicidin accelerated the rate of ATPase activity and reduced the H+/Pi ratio to 1.4. The results were found to be consistent with the chemiosmotic theory.

Fluoride inhibition of proton-translocating ATPases of oral bacteria [PDF]

Infection and Immunity, 1987
The ATPases of isolated membranes of lactic acid bacteria were found to be inhibited by fluoride in a complex manner. Among the enzymes tested, that of Streptococcus mutans GS-5 was the most sensitive to fluoride, and the initial rate of hydrolysis of ATP was reduced 50% by approximately 3 mM fluoride.

Topology of the Yeast Plasma Membrane Proton-translocating ATPase

Journal of Biological Chemistry, 1989
Four proteases have been used to assess the topology of the H+-ATPase from Saccharomyces cerevisiae reconstituted into phosphatidylserine vesicles. Limited proteolysis by trypsin and alpha-chymotrypsin inactivates the enzyme and produces stable, membrane-bound fragments. Sequence analyses of these peptides have located the peptide bonds hydrolyzed. The

Membrane-associated and Solubilized ATPases of Streptococcus mutans and Streptococcus sanguis

, 1987
The proton-translocating, membrane ATPases of oral streptococci have been implicated in cytoplasmic pH regulation, acidurance, and cariogenicity. Membranes were isolated from Streptococcus mutans GS-5 and Streptococcus sanguis NCTC 10904 following salt ...
