Shedding of genes that interfere with the pathogenic lifestyle: the Shigella model [0.03%]
基因脱落及其对病原生活方式的影响——志贺氏菌模型案例
Gianni Prosseda,Maria Letizia Di Martino,Rosaria Campilongo et al.
Gianni Prosseda et al.
Pathoadaptive mutations are evolutionary events leading to the silencing of specific anti-virulence loci. This reshapes the core genome of a novel pathogen, adapts it to the host and boosts its harmful potential. A paradigmatic case is the ...
Biochemical and genetic characteristics of Cronobacter sakazakii biofilm formation [0.03%]
阪崎肠杆菌菌群生化和基因特征分析
Xin-jun Du,Fei Wang,Xiaonan Lu et al.
Xin-jun Du et al.
Cronobacter sakazakii is a wide-spread opportunistic foodborne pathogen that can form biofilms on a number of different substances, creating food safety risk. However, there is little information about biofilm characteristics for this speci...
Synergistic effect of antimicrobial peptide arenicin-1 in combination with antibiotics against pathogenic bacteria [0.03%]
抗菌肽arenicin-1与抗生素联合应用对致病菌的协同作用

Shifts in phylogenetic diversity of archaeal communities in mangrove sediments at different sites and depths in southeastern Brazil [0.03%]
巴西东南部不同地点和深度红树林沉积物古菌群落的谱系多样性变化
Lucas William Mendes,Rodrigo Gouvêa Taketani,Acácio Aparecido Navarrete et al.
Lucas William Mendes et al.
This study focused on the structure and composition of archaeal communities in sediments of tropical mangroves in order to obtain sufficient insight into two Brazilian sites from different locations (one pristine and another located in an u...
A positive selection approach identifies residues important for folding of Salmonella enterica Pat, an N(ε)-lysine acetyltransferase that regulates central metabolism enzymes [0.03%]
一种阳性选择方法确定了调节三文鱼沙门氏菌中央代谢酶的N（ε）-赖氨酸乙酰转移酶Pat折叠的重要残基
Sandy Thao,Jorge C Escalante-Semerena
Sandy Thao
In Salmonella enterica, the protein acetyltransferase (Pat) enzyme is part of the sirtuin-dependent acylation/deacylation system (SDPADS) that modulates the activity of several proteins via the acylation of lysine residues critical to their...
Identification of the bacteriocin subtilosin A and loss of purL results in its high-level production in Bacillus amyloliquefaciens [0.03%]
枯草芽孢杆菌亚精胺素A的鉴定及purL基因丢失对其高效产生的影响
Quanli Liu,Guang Gao,Haijin Xu et al.
Quanli Liu et al.
A mini-Tn10 transposon mutagenesis library of strain Bacillus amyloliquefaciens BAhja NK10 was constructed and one mutant, L4, exhibiting markedly enhanced antagonistic activity against Micrococcus luteus, was screened and possessed an inac...
Involvement of the ammonium transporter AmtB in nitrogenase regulation and ammonium excretion in Pseudomonas stutzeri A1501 [0.03%]
AmtB铵转运蛋白参与施氏假单胞菌A1501氮固定酶的调节及铵盐排泄作用
Tao Zhang,Yongliang Yan,Sheng He et al.
Tao Zhang et al.
The nitrogen-fixing Pseudomonas stutzeri strain A1501 contains two ammonium transporter genes, amtB1 and amtB2, linked to glnK. Growth of an amtB1-amtB2 double deletion mutant strain was not impaired compared to that of the wild type under ...
Two sRNA RyhB homologs from Yersinia pestis biovar microtus expressed in vivo have differential Hfq-dependent stability [0.03%]
耶尔森菌生物种微小变种中两种RyhB的同源物在体内表达时具有不同的Hfq依赖稳定性
Zhongliang Deng,Xiangrong Meng,Shanchun Su et al.
Zhongliang Deng et al.
Small non-coding RNAs (sRNAs) have been shown to modulate gene expression at the post-transcriptional level. RyhB, an iron-responsive sRNA, is conserved in Escherichia coli and other Enterobacteriae, indicating the downregulation of numerou...
