ComX-induced exoproteases degrade ComX in Bacillus subtilis PS-216
Mihael Špacapan, Tjaša Danevčič, Ines Mandić-Mulec
Izvirni znanstveni članek
Oznake: mikrobne združbe;Bacillus subtilis;komunikacija med celicami;zaznavanje celične gostote;zaznavanje kvoruma;biofilmi;peptidi ComX;
Gram-positive bacteria use peptides as auto-inducing (AI) signals to regulate the production of extracellular enzymes (e.g., proteases). ComX is an AI peptide, mostly known for its role in the regulation of bacterial competence and surfactant production in Bacillus subtilis. These two traits are reg ...

Peptide signaling without feedback in signal production operates as a true quorum sensing communication system in Bacillus subtilis

Izvirni znanstveni članek
Oznake: Bacillus subtilis;komunikacija med celicami;zaznavanje kvoruma;signalni peptidi;
Bacterial quorum sensing (QS) is based on signal molecules (SM), which increase in concentration with cell density. At critical SM concentration, a variety of adaptive genes sharply change their expression from basic level to maximum level. In general, this sharp transition, a hallmark of true QS, r ...

Surfactin facilitates horizontal gene transfer in Bacillus subtilis
Tjaša Danevčič, Anna Oslizlo, Mihael Špacapan, Polonca Štefanič, Iztok Dogša, Ines Mandić-Mulec
Izvirni znanstveni članek
Oznake: Bacillus subtilis;zaznavanje kvoruma;horizontalni prenos genov;surfaktin;
Genetic competence for the uptake and integration of extracellular DNA is a key process in horizontal gene transfer (HGT), one of the most powerful forces driving the evolution of bacteria. In several species, development of genetic competence is coupled with cell lysis. Using Bacillus subtilis as a ...

ǂThe ǂComX quorum sensing peptide of Bacillus subtilis affects biofilm formation negatively and sporulation positively
Mihael Špacapan, Tjaša Danevčič, Polonca Štefanič, Michael Porter, Nicola R. Stanley-Wall, Ines Mandić-Mulec
Izvirni znanstveni članek
Oznake: mikrobne združbe;Bacillus subtilis;zaznavanje kvaruma;biofilm;sporulacija;surfaktin;
Quorum sensing (QS) is often required for the formation of bacterial biofilms and is a popular target of biofilm control strategies. Previous studies implicate the ComQXPA quorum sensing system of Bacillus subtilis as a promoter of biofilm formation. Here, we report that ComX signaling peptide defic ...

Po Gramu pozitivne bakterije uporabljajo peptide (autoinduktorje, AI) za medcelično komunikacijo, s katerimi lahko regulirajo številne prilagoditve na kritično celično gostoto populacije (kvorum). Obstoječe teorije in raziskave predpostavljajo, da AI signali in pripadajoči sistemi za zaznavanje k ...
