Biofilm formation is a well-known bacterial strategy that protects cells from hostile environments. During infection, bacteria found in a biofilm community are less sensitive to antibiotics and to the immune response, often allowing them to colonize ...

Tracking the Subcellular Localization of Surface Proteins in Staphylococcus aureus by Immunofluorescence Microscopy
Authors:  Salvatore J. Scaffidi, Mac A. Shebes and Wenqi Yu, date: 05/20/2021, view: 3330, Q&A: 0

Surface proteins of Staphylococcus aureus and other Gram-positive bacteria play essential roles in bacterial colonization and host-microbe interactions. Surface protein precursors containing a YSIRK/GXXS signal peptide are translocated across the

Assessment of Diadenylate Cyclase and c-di-AMP-phosphodiesterase Activities Using Thin-layer and Ion Exchange Chromatography
Authors:  Andreas Latoscha, David Jan Drexler, Gregor Witte and Natalia Tschowri, date: 01/05/2021, view: 1161, Q&A: 0

All living cells use cyclic nucleotides as second messengers for signal sensing and transduction. Cyclic di-3′,5′-adenosine monophosphate (c-di-AMP) is primarily involved in the control of bacterial and euryarcheal osmoadaptation and is
