BACKGROUND Bacillus subtilis is widely used in agriculture and industrial biotechnology; however, cell autolysis significantly decreases its yield in liquid cultures. Numerous factors mediate the lysis of B. subtilis, such as cannibalism factors, prophages, and peptidoglycan (PG) hydrolases. The aim of this work was to use molecular genetic techniques to develop a new strategy to prevent cell l...

The methyl parathion hydrolase (MPH)-encoding gene mpd was placed under the control of the P43 promoter and Bacillus subtilis nprB signal peptide-encoding sequence. High-level expression and secretion of mature, authentic, and stable MPH were achieved using the protease-deficient strain B. subtilis WB800 as the host.

Here, we present the genome sequence of Lactobacillus animalis strain P38 and Lactobacillus reuteri strain P43, both isolated from the cecum content of a 4-week old chicken fed a diet supplemented with the prebiotic β(1-4)galacto-oligosaccharide (GOS). These indigenous Lactobacillus isolates are potential probiotic organisms for poultry.

We determined that a pigeon cytochrome c-derived peptide, p43-58, possesses two anchor residues, 46 and 54, for binding with the I-Ab molecule that are compatible to the position 1 (P1) and position 9 (P9) of the core region in the major histocompatibility complex (MHC) class II binding peptides, respectively. In the present study to analyze each binding site between P1 and P9 of p43-58 to eith...

Knowledge of the molecular mechanisms that underlie neuron death after stroke is important to allow the development of effective neuroprotective strategies. In this study, we investigated the contribution of death receptor signaling pathways to neuronal death after ischemia using in vitro and in vivo models of ischemic injury and transgenic mice that are deficient in tumor necrosis factor recep...

AIMP1/p43 is known as a cytokine working in the control of angiogenesis, inflammation, and wound healing. Here we report its enrichment in pancreatic alpha cells and glucagon-like hormonal activity. AIMP1 is secreted from the pancreas upon glucose starvation. Exogenous infusion of AIMP1 increased plasma levels of glucose, glucagon, and fatty acid, and AIMP1-deficient mice showed reduced plasma ...

Let p43 be a prime, and Npð f ðxÞÞ denote the number of solutions of the congruence f ðxÞ 0 ðmod pÞ: In this paper, using the third-order recurring sequences we determine the values of Npðx þ a1x þ a2x þ a3Þ and Npðx þ ax þ bx þ cÞ; and construct the solutions of the corresponding congruences, where a1; a2; a3; a; b; c are integers. r 2003 Elsevier Science (USA).
