Gene Gangs of the Chloroviruses: Conserved Clusters of Collinear Monocistronic Genes
Viruses, 2018 Chloroviruses (family Phycodnaviridae) are dsDNA viruses found throughout the world’s inland waters. The open reading frames in the genomes of 41 sequenced chloroviruses (330 ± 40 kbp each) representing three virus types were analyzed for evidence of ...

A Coarse-Grained Biophysical Model of E. coli and Its Application to Perturbation of the rRNA Operon Copy Number [PDF]
PLoS Comput Biol. 2008 May 2;4(4):e1000038, 2010 We propose a biophysical model of Escherichia coli that predicts growth rate and an effective cellular composition from an effective, coarse-grained representation of its genome. We assume that E. coli is in a state of balanced exponential steadystate growth, growing in a temporally and spatially constant environment, rich in resources.

Engineering in Life Sciences, Volume 23, Issue 1, January 2023., 2023 Abstract Rationally designed synthetic microbial consortia carry a vast potential for biotechnological applications. The application of such a consortium in a bioprocess, however, requires tight and individual controllability of the involved microbes.

Engineering in Life Sciences, Volume 23, Issue 1, January 2023., 2023 Abstract Biotechnological production processes are sustainable approaches for the production of biobased components such as amino acids for food and feed industry. Scale‐up from ideal lab‐scale bioreactors to large‐scale processes is often accompanied by loss in productivity.

Impact of Salmonella genome rearrangement on gene expression
Evolution Letters, Volume 6, Issue 6, Page 426-437, December 2022., 2022 Abstract In addition to nucleotide variation, many bacteria also undergo changes at a much larger scale via rearrangement of their genome structure (GS) around long repeat sequences. These rearrangements result in genome fragments shifting position and/or orientation in the genome without necessarily affecting the underlying nucleotide sequence.

An NMR Study on the clpC Operon Binding Region of Transcription Factor CtsR from Bacillus subtilis
Chinese Journal of Magnetic Resonance, 2021 When Gram-positive bacterium Bacillus subtilis responds to heat-shock, protein arginine kinase McsB phosphorylates Arg62 (R) in the clpC operon binding region of transcription factor CtsR, leading to dissociation of CtsR and clpC operon and initiation of

Boolean models of the transport, synthesis, and metabolism of tryptophan in Escherichia Coli [PDF]
arXiv, 2022 The tryptophan (trp) operon in E. coli codes for the proteins responsible for the synthesis of the amino acid tryptophan from chorismic acid, and has been one of the most well-studied gene networks since its discovery in the 1960s. The tryptophanase (tna) operon codes for proteins needed to transport and metabolize it.

Probable Role of Type IV Pili of Aeromonas hydrophila in Human Pathogenicity
PathogensBackground: Aeromonas hydrophila is a widely recognized broad-spectrum pathogen that primarily targets the gastrointestinal tract. Type IV pili (T4P) are proteinaceous nano-machines located on the bacterial cell surface, playing a crucial role in host ...
