The Bacillus anthracis Exosporium: What’s the Big “Hairy” Deal?
ABSTRACT In some Bacillus species, including Bacillus subtilis , the coat is the outermost layer of the spore. In others, such as the Bacillus cereus family, there is an additional layer that envelops the coat, called the exosporium. In the case of

Analysis of the glycoprotein content of wild-type and ΔywdL exosporium.
(A) Western blot analysis with anti-BclA antibodies. Lane 1 shows negative control (vegetative cells), lane 2 and 3 unwashed and fully washed B. cereus wild-type exosporium and lanes 4 and 5 show unwashed and fully washed ΔywdL exosporium respectively ...

Orthologues of Bacillus subtilis Spore Crust Proteins Have a Structural Role in the Bacillus megaterium QM B1551 Spore Exosporium. [PDF]
The exosporium of Bacillus megaterium QM B1551 spores is morphologically distinct from exosporia observed for the spores of many other species. Previous work has demonstrated that unidentified genes carried on one of the large indigenous plasmids are ...

Phylogenomic analysis of the collagen-like BclA proteins in Clostridioides difficile
Clostridioides difficile is a Gram-positive, anaerobic, spore-forming bacterium and a major nosocomial pathogen, notable for its high genetic diversity. C.

YabG is a sporulation‐specific protease that processes cortex‐destined proteins in Clostridioides difficile. Mutations in the promoter region of C. difficile yabG resulted in either high early stage expression or undetectable levels of expression. YabG cleaves the spore cortex lytic enzyme preproSleC to proSleC, which is incorporated into mature spores,

Ultrastructure of the Exosporium and Underlying Inclusions in Spores of Bacillus megaterium Strains [PDF]
Spores of selected strains of Bacillus megaterium were prepared by various methods and examined with the electron microscope. An exosporium like that of B. cereus , with a nap and basal layer, was found in spores of a B.

The role of endospore appendages in spore–spore interactions in the pathogenic Bacillus cereus group
This study demonstrates that the aggregation of endospores is facilitated through endospore appendages, also known as ENAs. It highlights the significance of the ENA tip‐fibrilla, particularly the L‐BclA, which forms the tip fibrillum of the L‐ENA, as the functional part of the fibre.

The bacterial Pro‐Pro endopeptidases (PPEPs) possess the unique ability to hydrolyze proline‐proline bonds. We profiled the full substrate specificity of PPEPs in detail using a combination of synthetic combinatorial peptides and mass spectrometry. With this method, we determined the specificity of previously characterized PPEPs, PPEP mutants, and ...
