Bacteriophage 434 Hex Protein Prevents RecA-Mediated Repressor Autocleavage

Viruses, 2013
In a λimm434 lysogen, two proteins are expressed from the integrated prophage. Both are encoded by the same mRNA whose transcription initiates at the PRM promoter. One protein is the 434 repressor, needed for the establishment and maintenance of

What is Life? [PDF]

, 2020
In searching for life in extraterrestrial space, it is essential to act based on an unequivocal definition of life. In the twentieth century, life was defined as cells that self-replicate, metabolize, and are open for mutations, without which genetic ...

Proteome Analysis of Corynebacterium diphtheriae–Macrophage Interaction

PROTEOMICS, EarlyView.
ABSTRACT Contact of Corynebacterium diphtheriae with macrophages induces adaptations on both bacterial and cellular sides. The study presented here was aiming to shed light on the simultaneous intracellular adaptation of the bacteria and changes in the proteome of the phagocytes in response to the internalization of C. diphtheriae.

Diversity and Host Interactions among Virulent and Temperate Baltic Sea Flavobacterium Phages

Viruses, 2020
Viruses in aquatic environments play a key role in microbial population dynamics and nutrient cycling. In particular, bacteria of the phylum Bacteriodetes are known to participate in recycling algal blooms.

From DNA sequence to application: possibilities and complications [PDF]

, 1999
The development of sophisticated genetic tools during the past 15 years have facilitated a tremendous increase of fundamental and application-oriented knowledge of lactic acid bacteria (LAB) and their bacteriophages.

Cell‐in‐Bead‐in‐Droplet Platform for pH‐Based Microfluidic Screening of Ureolytic Bacteria

Small, EarlyView.
Efficient high‐throughput microbial screening in droplet microfluidics is often challenged by chemical crosstalk between droplets. This is particularly difficult in pH‐changing biological processes, for which more effective biochemical assays are needed.

Transcriptional delay stabilizes bistable gene networks

, 2013
Transcriptional delay can significantly impact the dynamics of gene networks. Here we examine how such delay affects bistable systems. We investigate several stochastic models of bistable gene networks and find that increasing delay dramatically ...

Identification of QuiP, the Product of Gene PA1032, as the Second Acyl-Homoserine Lactone Acylase of Pseudomonas aeruginosa PAO1 [PDF]

, 2006
The relevance of the acyl homoserine lactone (acyl-HSL) quorum signals N-3-oxododecanoyl-homoserine lactone (3OC12HSL) and N-butanoyl-homoserine lactone to the biology and virulence of Pseudomonas aeruginosa is well investigated.

Motorized DNAzymes Drive Enhanced Electrochemical Biosensing for Rapid Bacterial Detection

Small Methods, EarlyView.
The micromotor DNAzyme analyzer (Motolyzer) enables sensitive electrochemical detection of Legionella pneumophila proteins in unprocessed samples with high specificity. Upon target recognition, DNAzymes actively release redox barcodes, which are detected on DNA‐functionalized electrodes.

Lysogeny in Leuconostocs

Nihon Chikusan Gakkaiho, 1980
Lactic streptococciおよびlactobacilliの溶原性についていくつかの報告が行われているが,leuconostoc菌種の溶原性についての報告は,著者らが知るかぎりにおいて見い出せない.本報告は,leuconostoc菌種の溶原性の検索を目的としleuconostoc 32菌株をマイトマイシンC処理により,その溶原性の有無を調べた.Leuconostoc菌株の溶原性のマイトマイシンCによる誘発は,その濃度に大きく依存しまたマイトマイシンCに対する感受性は,leuconostoc菌株によってことなった.Leuconostoc菌株を培養し対数期初期にマイトマイシンCを液体培地1ml当り最終濃度0.5μgおよび5.0μg加えて溶原菌株の誘発を行った.Leuconostoc ...
