Journal ArticleDOI
A eukaryotic-like Ser/Thr kinase signals bacteria to exit dormancy in response to peptidoglycan fragments
TL;DR: Staurosporine acts by blocking germination of dormant spores of dormant Bacillus subtilis spores by blocking muropeptide-dependent germination.
Journal ArticleDOI
Exit from dormancy in microbial organisms
Jonathan Dworkin,Ishita M. Shah +1 more
TL;DR: It is proposed that many microorganisms exit dormancy in response to cell wall muropeptides, and may sense when conditions have improved and re-initiate growth, lest they be outcompeted by their neighbours.
Journal ArticleDOI
Induction and regulation of a secreted peptidoglycan hydrolase by a membrane Ser/Thr kinase that detects muropeptides
Ishita M. Shah,Jonathan Dworkin +1 more
TL;DR: It is hypothesized that YocH is used by the Bacillus subtilis bacterium to digest peptidoglycan released by other bacteria in the milieu and that the presence of these fragments is detected by a membrane kinase that modifies a key regulator of translation as well as to stimulate its own expression.
Journal ArticleDOI
Synthetic peptidoglycan motifs for germination of bacterial spores.
TL;DR: Supernatants from cultures of growing bacteria and constituents of the cell wall could serve as germinants of dormant B. subtilis and B. anthracis spores, and the presence of these molecules in the milieu as germination signals might be physiologically relevant.
Journal ArticleDOI
Superdormant Spores of Bacillus Species Germinate Normally with High Pressure, Peptidoglycan Fragments, and Bryostatin
TL;DR: Superdormant spores of Bacillus cereus and Bacillus subtilis germinated just as well as dormant spores with pressures of 150 or 500 MPa and with or without heat activation.
