Poly-γ-Glutamic Acids Contribute to Biofilm Formation and Plant Root Colonization in Selected Environmental Isolates of Bacillus subtilis
Bacillus subtilis is long known to produce poly-γ-glutamic acids (γ-PGA) as one of the major secreted polymeric substances. In B. subtilis, the regulation of γ-PGA production and its physiological role are still unclear. B. subtilis is also capable of forming structurally complex multicellular communities, or biofilms, in which an extracellular matrix consisting of secreted proteins and polysac...
متن کاملDistinct and essential morphogenic functions for wall- and lipo-teichoic acids in Bacillus subtilis.
Teichoic acids (TAs) are anionic polymers that constitute a major component of the cell wall in most Gram-positive bacteria. Despite decades of study, their function has remained unclear. TAs are covalently linked either to the cell wall peptidoglycan (wall TA (WTA)) or to the membrane (lipo-TA (LTA)). We have characterized the key enzyme of LTA synthesis in Bacillus subtilis, LTA synthase (Lta...
متن کاملWall Teichoic Acid Glycosylation Governs Staphylococcus aureus Nasal Colonization
UNLABELLED Nasal colonization by the human pathogen Staphylococcus aureus is a major risk factor for hospital- and community-acquired infections. A key factor required for nasal colonization is a cell surface-exposed zwitterionic glycopolymer, termed wall teichoic acid (WTA). However, the precise mechanisms that govern WTA-mediated nasal colonization have remained elusive. Here, we report that ...
متن کاملFunction of alpha-D-glucosyl monophosphorylpolyprenol in biosynthesis of cell wall teichoic acids in Bacillus coagulans.
D-[alpha-14C]]glucosyl phosphorylpolyprenol ([ 14C]Glc-P-prenol) was formed from UDP-D-[14C]glucose in each of the membrane systems obtained from Bacillus coagulans AHU 1631 and AHU 1634 and two Bacillus megaterium strains. Membranes of these B. coagulans strains, which possess beta-D-glucosyl branches on the repeating units in their major cell wall teichoic acids, were shown to catalyze the tr...
متن کاملWall teichoic acid polymers are dispensable for cell viability in Bacillus subtilis.
An extensive literature has established that the synthesis of wall teichoic acid in Bacillus subtilis is essential for cell viability. Paradoxically, we have recently shown that wall teichoic acid biogenesis is dispensable in Staphylococcus aureus (M. A. D'Elia, M. P. Pereira, Y. S. Chung, W. Zhao, A. Chau, T. J. Kenney, M. C. Sulavik, T. A. Black, and E. D. Brown, J. Bacteriol. 188:4183-4189, ...
