A Novel Cryptic Clostridial Peptide That Kills Bacteria by a Cell Membrane Permeabilization Mechanism
PublicationThis work reports detailed characteristics of the antimicrobial peptide Intestinalin (P30), which is derived from the LysC enzyme of Clostridium intestinale strain URNW. The peptide shows a broader antibacterial spectrum than the parental enzyme, showing potent antimicrobial activity against clinical strains of Gram-positive staphylococci and Gram-negative pathogens and causing between 3.04 ± 0.12 log kill for Pseudomonas aeruginosa...

Phosphorylation‐mediated regulation of heat shock response in Escherichia coli
PublicationEscherichia coli has two heat shock regulons under the transcriptional control of Esigma(32) and Esigma(E) RNA polymerases. These polymerases control the expression of genes, the products of which are needed for correct folding of proteins in the cytoplasm and the extracytoplasm respectively. In this study, we report that mutations in a tyrosine phosphatase-encoding gene led to decreased activity of these heat shock regulons. The...

Novel thermostable single-stranded DNA-binding protein (SSB) from Deinococcus geothermalis
PublicationW celu zbadania właściwości biochemicznych białka wiążącego się do jednoniciowego DNA (SSB) pochodzącego z Deinococcus geothermalis (DgeSSB), sklonowano gen ssb otrzymany w reakcji PCR, a następnie uzyskano wydajną biosyntezę białka DgeSSB. Gen składa się z 900 par zasad, kodujących białko złożone z 300 reszt aminokwasowych, o wyliczonej masie molekularnej równej 32.45 kDa. Sekwencja aminokwasowa wykazuje 43, 44% i 75% identyczności...

A new cold-adapted beta-D-galactosidase from the Antarctic Arthrobacter sp. 32c - gene cloning, overexpression, purification and properties
PublicationThe development of a new cold-active β-D-galactosidases and microorganisms that efficiently ferment lactose is of high biotechnological interest, particularly for lactose removal in milk and dairy products at low temperatures and for cheese whey bioremediation processes with simultaneous bio-ethanol production. In this article, we present a new β-D-galactosidase as a candidate to be applied in the above mentioned biotechnological...
