PROTEIN BIOTECHNOLOGY: THE SIGNIFICANCE AND USE OF INDUSTRIAL POLYMER-DEGRADING ENZYMES [PDF]
مجلة جامعة كركوك للعلوم الزراعيةMicroorganisms are the primary source of industrial enzymes, with Bacillus and Aspergillus species being the leading producers. Bacillus strains have historically been used to synthesize commercially significant enzymes due to their status as GRAS ...

DNA looping: the consequences and its control [PDF]
Curr. Opin. Struct. Biol. 16, 344-350 (2006), 2006 The formation of DNA loops by proteins and protein complexes is ubiquitous to many fundamental cellular processes, including transcription, recombination, and replication. Here we review recent advances in understanding the properties of DNA looping in its natural context and how they propagate to the cellular behavior through gene regulation.

Complementary Theory of Evolutionary Genetics [PDF]
arXiv, 2021 This theory seeks to define species and to explore evolutionary forces and genetic elements in speciation and species maintenance. The theory explains how speciation and species maintenance are caused by natural selection acting on non-Mendelian and Mendelian variation, respectively. The emergence and maintenance of species as groups of populations are

DNA looping in gene regulation: from the assembly of macromolecular complexes to the control of transcriptional noise [PDF]
Current Opinion in Genetics & Development, 15, 136-144 (2005), 2005 The formation of DNA loops by proteins and protein complexes that bind at distal DNA sites plays a central role in many cellular processes, such as transcription, recombination, and replication. Here we review the basic thermodynamic concepts underlying the assembly of macromolecular complexes on looped DNA and the effects that this process has in the ...

Physics of RecA-mediated homologous recognition [PDF]
, 2004 Most proteins involved in processing DNA accomplish their activities as a monomer or as a component of a multimer containing a relatively small number of other elements. They generally act locally, binding to one or a few small regions of the DNA substrate. Striking exceptions are the \textit{E.

Making tau amyloid models in vitro: a crucial and underestimated challenge
FEBS Letters, EarlyView.This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...
