Temporal and spatial regulation of protein cross-linking by the pre-assembled substrates of a Bacillus subtilis spore coat transglutaminase. [PDF]

PLoS Genetics, 2019
In many cases protein assemblies are stabilized by covalent bonds, one example of which is the formation of intra- or intermolecular ε-(γ-glutamyl)lysil cross-links catalyzed by transglutaminases (TGases).

Diversity and evolutionary dynamics of spore-coat proteins in spore-forming species of Bacillales. [PDF]

Microb Genom, 2020
Among members of the Bacillales order, there are several species capable of forming a structure called an endospore. Endospores enable bacteria to survive under unfavourable growth conditions and germinate when environmental conditions are favourable again.

Electron Beam Irradiation Dose Dependently Damages the Bacillus Spore Coat and Spore Membrane [PDF]

International Journal of Microbiology, 2012
Effective control of spore-forming bacilli begs suitable physical or chemical methods. While many spore inactivation techniques have been proven effective, electron beam (EB) irradiation has been frequently chosen to eradicate Bacillus spores.

Phosphorylation of spore coat proteins by a family of atypical protein kinases. [PDF]

Proc Natl Acad Sci U S A, 2016
The modification of proteins by phosphorylation occurs in all life forms and is catalyzed by a large superfamily of enzymes known as protein kinases. We recently discovered a family of secretory pathway kinases that phosphorylate extracellular proteins ...

Constructing fluorogenic Bacillus spores (F-spores) via hydrophobic decoration of coat proteins. [PDF]

PLoS ONE, 2010
Bacterial spores are protected by a coat consisting of about 60 different proteins assembled as a biochemically complex structure with intriguing morphological and mechanical properties.

Functional characterization of Clostridium difficile spore coat proteins. [PDF]

J Bacteriol, 2013
ABSTRACT Spores of Clostridium difficile play a key role in the dissemination of this important human pathogen, and until recently little has been known of their functional characteristics.

Molecular architecture of the assembly of Bacillus spore coat protein GerQ revealed by cryo-EM [PDF]

Nature Communications
Protein filaments are ubiquitous in nature and have diverse biological functions. Cryo-electron microscopy (cryo-EM) enables the determination of atomic structures, even from native samples, and is capable of identifying previously unknown filament ...

Bioremediation and Recovery of Lead and Cadmium by Spores of Bacillus subtilis C1 [PDF]

MicrobiologyOpen
Spores of a hot spring isolated strain of Bacillus subtilis were tested as a biotechnological tool to be used for the detoxification and bioremedition of heavy metals. Lead and cadmium were efficiently adsorbed by B. subtilis spores with those of C1 more

The Direct Interaction between Two Morphogenetic Proteins Is Essential for Spore Coat Formation in Bacillus subtilis. [PDF]

PLoS ONE, 2015
In Bacillus subtilis the protective layers that surround the mature spore are formed by over seventy different proteins. Some of those proteins have a regulatory role on the assembly of other coat proteins and are referred to as morphogenetic factors ...

Combination of fluorescent reagents with 2-(4-aminophenyl) benzothiazole and safranin O was useful for analysis of spore structure, indicating the diversity of Bacillales species spores [PDF]

Frontiers in Microbiology
BackgroundSafranin O is commonly used for the gram staining of bacteria and fluorescent staining of plant tissues. We aimed to perform a more detailed structural analysis of bacterial spores by analyzing the staining pattern of safranin O, together with ...
