The structure of a polymer containing galactosamine from walls of Bacillus subtilis 168.

ABSTRACT: Cell walls of Bacillus subtilis 168 contain a phosphorylated polysaccharide composed of N-acetylgalactosamine, glucose and phosphate. Controlled acid hydrolysis gives 3-O-beta-d-glucopyranosyl-N-acetylgalactosamine with a phosphomonoester group at the 6-position of glucose. It is likely that the polysaccharide consists of disaccharide units connected by phosphodiester residues joining the 1-position of N-acetylgalactosamine to the 6-position of glucose in the neighbouring unit.

The location of N-acetylgalactosamine in the walls of Bacillus subtilis 168.

Project description:The N-acetylgalactosamine in the walls of Bacillus subtilis 168 occurs in two polymers. One of these contains N-acetylgalactosamine, glucose and phosphorus and is attached to the peptidoglycan through an alkali-labile bond; preliminary studies indicate that a repeating unit of this polymer is glucosyl-N-acetylgalactosamine 1-phosphate. N-Acetylgalactosamine is also associated with the peptidoglycan in a component that is not converted into the free sugar or other soluble compounds on treatment of the walls with alkali. The two polymers containing N-acetylgalactosamine are released on autolysis of the walls and can be separated by ion-exchange chromatography. As glucose 6-phosphate is produced by gentle hydrolysis of the wall with acid a third phosphate polymer, poly(glucose 1-phosphate), may occur in this wall. However, as no polymer with this structure could be separated from that containing galactosamine, its existence has not been established unequivocally. The methods described permit the study of variations in N-acetylgalactosamine content with respect to growth conditions.

Engineering of Bacillus subtilis 168 for increased nisin resistance.

Project description:Nisin is a natural bacteriocin produced commercially by Lactococcus lactis and widely used in the food industry as a preservative because of its broad host spectrum. Despite the low productivity and troublesome fermentation of L. lactis, no alternative cost-effective host has yet been found. Bacillus subtilis had been suggested as a potential host for the biosynthesis of nisin but was discarded due to its sensitivity to the lethal action of nisin. In this study, we have reevaluated the potential of B. subtilis as a host organism for the heterologous production of nisin. We applied transcriptome and proteome analyses of B. subtilis and identified eight genes upregulated in the presence of nisin. We demonstrated that the overexpression of some of these genes boosts the natural defenses of B. subtilis, which allows it to sustain higher levels of nisin in the medium. We also attempted to overcome the nisin sensitivity of B. subtilis by introducing the nisin resistance genes nisFEG and nisI from L. lactis under the control of a synthetic promoter library.

Bacillus subtilis WalR (YycF) ChIP-chip Bacillus subtilis; Bacillus subtilis subsp. subtilis str. 168

Project description:Identification of the specific WalR (YycF) binding regions on the B. subtilis chromosome during exponential and phosphate starvation growth phases. The data serves to extend the WalRK regulon in Bacillus subtilis and its role in cell wall metabolism, as well as implying a role in several other cellular processes. For each sample analyzed in this study three biological replicates were performed. Three different samples were taken from a strain expressing the WalR-SPA protein as well as from wild-type (168) without a tagged WalR. Samples were taken from exponentially growing cells in low phosphate medium (LPDM) as well as from phosphate-limited cells (T2). Each sample compares ChIP DNA vs. Total DNA from the same cells.

The condition-dependent transcriptome of Bacillus subtilis 168

Project description:Recent studies revealed the unsuspected complexity of the bacterial transcriptome but its systematic analysis across many diverse conditions remains a challenge. Here we report the condition-dependent transcriptome of the prototype strain B. subtilis 168 across 104 conditions reflecting the bacterium's life-styles. This data set composed of 269 tiling array hybridizations allowed to observe ~85% of the annotated CDSs expressed in the higher 30% in at least one hybridization and thus provide an excellent coverage of the transcriptome of this bacterium. In addition to the Genbank annotation 1583 new segments of the chromosome were identified as transcribed and have transcription levels reported in the data matrix.
