Aliaksandra Herasimovich et al.
Lactococcus phages that belong to the genus Ceduovirus are among the three most frequently isolated phage groups infecting Lactococcus lactis starter strains in dairy plants. In this study, we characterized virulent Lactococcus phage BIM BV...
Isolation of a PRD1-like phage uncovers the carriage of three putative conjugative plasmids in clinical Burkholderia contaminans [0.03%]
一种PRD1类似的噬菌体的分离揭示了临床Burkholderia contaminans中携带三个假定的接合质粒

Cassandra R Stanton
The Burkholderia cepacia complex (Bcc) is a group of increasingly multi-drug resistant opportunistic bacteria. This resistance is driven through a combination of intrinsic factors and the carriage of a broad range of conjugative plasmids ha...
Multiple SigB homologues govern the transcription of the ssgBp promoter in the sporulation-specific ssgB gene in Streptomyces coelicolor A3(2) [0.03%]
多重SigB同源物调控链霉菌孢子形成特异基因ssgB的启动子ssgBp的转录
Rachel Javorova,Beatrica Sevcikova,Bronislava Rezuchova et al.
Rachel Javorova et al.
Unlike Bacillus subtilis, Streptomyces coelicolor contains nine SigB homologues of the stress-response sigma factor SigB. By using a two-plasmid system, we previously identified promoters recognized by these sigma factors. Almost all promot...

Antimicrobial resistance is one of the leading causes of death worldwide and research on this topic has been on the spotlight for a long time. More recently and in agreement with the One Health Approach, the focus has moved towards the envi...
Biochemical characterization and mutational analysis of the NurA protein from the hyperthermophilic euryarchaeon Thermococcus barophilus Ch5 [0.03%]
来自极端嗜热广古菌Thermococcus barophilus Ch5的NurA蛋白的生化特征和突变分析
Guangyu Ma,Tan Lin,Peng Cao et al.
Guangyu Ma et al.
Archaeal NurA protein plays a key role in producing 3'-single stranded DNA used for homologous recombination repair, together with HerA, Mre11, and Rad50. Herein, we describe biochemical characteristics and roles of key amino acid residues ...
The murein endopeptidase MepA regulated by MtrAB and MprAB participate in cell wall homeostasis [0.03%]
由MtrAB和MprAB调节的肽聚糖内肽酶MepA参与细胞壁稳态
Feng Peng,Yu Zou,Xiuxia Liu et al.
Feng Peng et al.
The complete genome of Corynebacterium glutamicum contain a gene encoding murein endopeptidase MepA which maintain cell wall homeostasis by regulating peptidoglycan biosynthesis. In this study, we investigate the physiological function, loc...
Effects of ultraviolet and photosynthetically active radiation on morphogenesis, antioxidants and photoprotective defense mechanism in a hot-spring cyanobacterium Nostoc sp. strain VKB02 [0.03%]
紫外线和光合辐射对热泉蓝藻Nostoc孢子株VKB02的形态发生，抗氧化剂和光保护防御机制的影响

The continuous increase in global temperature and ultraviolet radiation (UVR) causes profound impacts on the growth and physiology of photosynthetic microorganisms. The hot-spring cyanobacteria have a wide range of mitigation mechanisms to ...
Elevated concentrations of polymyxin B elicit a biofilm-specific resistance mechanism in Vibrio cholerae [0.03%]
多粘菌素B的浓度升高会引发霍乱弧菌产生一种与生物膜相关的特异性耐药机制

Vibrio cholerae can form biofilms in the aquatic environment and in the human intestine, facilitating the release of hyper-infectious aggregates. Due to the increasing antibiotic resistance, alternatives need to be found. One of these alter...
The role of intracellular β-glucosidase in cellulolytic response induction in filamentous fungus Penicillium verruculosum [0.03%]
室内β-葡萄糖苷酶在丝状真菌Penicillium verruculosum纤维素降解反应诱导中的作用

Valeriy Yu Kislitsin et al.
In this study, CRISPR/Cas9 genome editing was used to knockout the bgl2 gene encoding intracellular β-glucosidase filamentous fungus Penicillium verruculosum. This resulted in a dramatic reduction of secretion of cellulolytic enzymes. The ...
