Three Yersinia enterocolitica AmpD Homologues Participate in the Multi-step Regulation of chromosomal cephalosporinase, AmpC

open access: yesFrontiers in Microbiology, 2016
In many gram negative bacilli, AmpD plays a key role in both cell well recycling pathway and β-lactamase regulation, inactivation of the ampD causes the accumulation of 1,6-anhydromuropeptides and results in the ampC overproduction.

Beta-lactamase induction and cell wall metabolism in Gram-negative bacteria

open access: yesFrontiers in Microbiology, 2013
Production of beta-lactamases, the enzymes that degrade beta-lactam antibiotics, is the most widespread and threatening mechanism of antibiotic resistance.

Electron spin resonance for the detection of long-range spin nematic order

open access: yes, 2018
In this paper we propose that electron spin resonance (ESR) measurements enable us to detect the long-range spin nematic order. We show that the frequency of the paramagnetic resonance peak in the ESR spectrum is shifted by the ferroquadrupolar order ...

Complete genome sequence of the multiresistant taxonomic outlier Pseudomonas aeruginosa PA7.

open access: yesPLoS ONE, 2010
Pseudomonas aeruginosa PA7 is a non-respiratory human isolate from Argentina that is multiresistant to antibiotics. We first sequenced gyrA, gyrB, parC, parE, ampC, ampR, and several housekeeping genes and found that PA7 is a taxonomic outlier. We report

AmpG在AmpC酶表达中的调控作用及研究进展

open access: yesZhongguo shiyan zhenduanxue, 2012
AmpC酶,是由革兰氏阴性菌产生的一种β-内酰胺酶[1]。近年来,由于β-内酰胺类抗菌药物的过度使用,使得β-内酰胺酶介导的耐药情况越来越严重,最终给临床抗菌药物的选择和治疗带来了困难[2]。AmpC酶能够水解三代头孢菌素酶,单环类和头霉素类抗生素,而且不受酶抑制剂所抑制[3,5]。AmpC酶的作用机制目前还没有完全确定,它的出现与细胞壁肽聚糖循环相关,至少有四个基因参与了AmpC酶的表达,分别为ampR,ampD,ampG和ampE,其中ampR和ampD的相关性研究较多 ...

Single-Input Regulatory Cascade for in vivo Removal of the Solubility Tag in Fusion Recombinant Proteins Produced by Escherichia coli

open access: yesFrontiers in Bioengineering and Biotechnology, 2019
Solubility tags are commonly fused to target recombinant proteins to enhance their solubility and stability. In general, these protein tags must be removed to avoid misfolding of the partner protein and to allow for downstream applications. Nevertheless,
