Estudo dos antiporters Na+/H+ NhaC e NhaE de Neisseria meningitidis [PDF]
, 2013 Os antiporters Na+/H+ são proteínas membranares, encontradas em todos os reinos e envolvidas na homeostasia do Na+ e do pH. Dois antiporters Na+/H+, denominados NmNhaC e NmNhaE foram identificados no genoma da bactéria patogénica, Neisseria meningitidis,

Cation/proton antiport systems in Escherichia coli. Properties of the potassium/proton antiporter.
Journal of Biological Chemistry, 1980 The potassium/proton antiport system of Escherichia coli has been characterized by the effect of monovalent cations on the pH gradient formed by oxidation of lactate in everted membrane vesicles. Substrates of the system include K+, Na+, Li+, Rb+, and Tl+. The antiporter could also be assayed by uptake of 204Tl+ into everted vesicles.

The Oral‐Gut Axis: Bidirectional Interactions Between Microbiome and Diseases
Journal of Periodontal Research, EarlyView.This study aims to summarize the mechanisms underlying ectopic colonization of the gut by oral pathobionts and the microbial and host factors that regulate this process. ABSTRACT Increased colonization of typically oral microorganisms is frequently observed in the gut mucosa or lumen of individuals with gastrointestinal disorders, including patients ...

Lotus tenuis tolerates combined salinity and waterlogging: maintaining O2 transport to roots and expression of an NHX1-like gene contribute to regulation of Na+ transport [PDF]
, 2010 Salinity and waterlogging interact to reduce growth for most crop and pasture species. The combination of these stresses often cause a large increase in the rate of Na+ and Cl− transport to shoots; however, the mechanisms responsible for this are largely

Molecular Microbiology, EarlyView.YdcI, a LysR‐type transcription regulator in Escherichia coli, regulates loci like iraP and mqo. Its expression is induced by (p)ppGpp under stress conditions, and protein levels rise during mid‐exponential growth, connecting its role to stress response and metabolism control. ABSTRACT YdcI, a LysR‐type transcription regulator, has been associated with

Sodium/proton antiporter in Streptococcus faecalis [PDF]
Journal of Bacteriology, 1987 Streptococcus faecalis, like other bacteria, accumulates potassium ions and expels sodium ions. This paper is concerned with the pathway of sodium extrusion. Earlier studies (D.L. Heefner and F.M. Harold, Proc. Natl. Acad. Sci. USA 79:2798-2802, 1982) showed that sodium extrusion is effected by a primary, ATP-linked sodium pump.

New Phytologist, EarlyView.Identification of new regulators of Arabidopsis IRT1 endocytosis and metal transport using TurboID. TurboID proximity labeling of the Arabidopsis IRT1 root metal transporter identified new IRT1‐interacting proteins upon different metal regimes. Among validated candidates, the endosome‐localized NHX5 Na+ (K+)/H+ antiporter and the plasma membrane ...

Protein phylogenetic analysis of Ca2+/cation antiporters and insights into their evolution in plants
Frontiers in Plant Science, 2012 Cation transport is a critical process in all organisms and is essential for mineral nutrition, ion stress tolerance, and signal transduction. Transporters that are members of the Ca2+/Cation Antiporter (CaCA) superfamily are involved in the transport of

New Phytologist, EarlyView.Salinity reduces duckweed growth responses. Summary Salinity is one of the main environmental factors limiting the performance of duckweeds and despite growing ecological and biotechnological interest in these macrophytes, there is a lack of quantitative analyses of their responses to sodium chloride.
