NhaA Na+/H+ antiporter mutants that hardly react to the membrane potential. [PDF]

PLoS One, 2014
pH and Na+ homeostasis in all cells requires Na+/H+ antiporters. The crystal structure, obtained at pH 4, of NhaA, the main antiporter of Escherichia coli, has provided general insights into an antiporter mechanism and its unique pH regulation.

EP432 HPV 18 predicts worse prognosis in patients with cervical cancer treated with chemoradiotherapy

ePoster, 2019
Introduction/Background Studies have shown that high-risk HPV plays an important role in tumorigenesis. However, the significance of HPV type in the prediction of treatment outcomes of cervical cancer patients is still controversial. This study was designed to evaluate the prognostic value of pre-treatment HPV DNA in correlation to long-term survival.

Molecular characterization of PeNhaD1: the first member of the NhaD Na+/H+ antiporter family of plant origin

, 2005
PeNhaD1 encodes a putative Na+/H+ antiporter from the salt-resistant tree Populus euphratica. It is the first characterization of a member of the NhaD type ion transporter family of plant origin.

The Na+ and K+ transport deficiency of an E. coli mutant lacking the NhaA and NhaB proteins is apparent and caused by impaired osmoregulation

, 1998
Cells of the E. coli mutant EP432, which lacks the two Na+/H+ antiporters, NhaA and NhaB, have been reported to have an impaired sodium transport activity (Harel-Bronstein et al. (1995) J. Biol. Chem. 270, 3816–3822). Here we report that active transport

A167P NhaA mutant growth and expression.

, 2014
(A) The double mutant A167P (TM V)-N359D (TM XII) and the previously [24] isolated mutant F267C (TM IX) are shown in red (ball and stick) on the NhaA structure without TM I, for clarity (ribbon presentation by PyMol). Asp163 and Asp164 are shown in black

pH dependence of the Na⁺, Li⁺/H⁺ antiporter activity in everted membrane vesicles of variant A167P.

, 2014
Everted membrane vesicles were prepared from EP432 cells grown in LBK (pH 7) and expressing WT (□) or A167P (Δ). The Na+/H+ and Li+/H+ antiporter activity was determined in the presence of 10 mM NaCl (filled symbols) or 10 mM LiCl (open symbols) at the ...

Functional characterization of a NapA Na(+)/H(+) antiporter from Thermus thermophilus.

, 2007
Na(+)/H(+) antiporters are ubiquitous membrane proteins and play an important role in cell homeostasis. We amplified a gene encoding a member of the monovalent cation:proton antiporter-2 (CPA2) family (TC 2.A.37) from the Thermus thermophilus genome and ...

Calcium transport mediated by NhaA, a Na+/H+ antiporter from Escherichia coli

, 1993
In everted membrane vesicles of E. coli strain EP432/pGM42, which has only one Na+/H+ antiporter (NhaA), external CaC4 inhibits dissipation of the respiration-dependent ΔpH in response to the addition of NaCl at pH 7.5, and decreases equilibrium ...
