Thermostable Mn-dependent catalases are promising enzymes in biotechnological applications as H(2)O(2)-detoxifying systems. We cloned the genes encoding Mn-dependent catalases from Thermus thermophilus HB27 and HB8 and a less thermostable mutant carrying two amino acid replacements (M129V and E293G). When the wild-type and mutant genes were overexpressed in Escherichia coli, unmodified or six-H...
BACKGROUND ExCyto PCR cells provide a novel and cost effective means to amplify DNA transformed into competent bacterial cells. ExCyto PCR uses host E. coli with a chromosomally integrated gene encoding a thermostable DNA polymerase to accomplish robust, hot-start PCR amplification of cloned sequences without addition of exogenous enzyme. RESULTS Because the thermostable DNA polymerase is sta...
To study the effect of inserted peptides on the secretion and processing of exported proteins in Bacillus subtilis and Escherichia coli, pBR322-derived DNA fragments coding for small peptides were inserted between the DNA coding for the 31 amino acid B. subtilis alpha-amylase signal peptide and that coding for the mature part of the extracellular thermostable alpha-amylase of B. stearothermophi...
BACKGROUND Foodborne illness can occur due to various pathogenic bacteria such as Staphylococcus aureus, Escherichia coli and Vibrio parahaemolyticus, and can cause severe gastroenteritis symptoms. In this study, we completed the genome sequence of a foodborne pathogen V. parahaemolyticus FORC_014, which was isolated from suspected contaminated toothfish from South Korea. Additionally, we exten...
Our previous molecular epidemiologic study with gene probes (H. Shirai, H. Ito, T. Hirayama, Y. Nakamoto, N. Nakabayashi, K. Kumagai, Y. Takeda, and M. Nishibuchi, Infect. Immun. 58:3568-3573, 1990) demonstrated that the gene (trh) encoding a thermostable direct hemolysin-related hemolysin was strongly associated with clinical strains of Vibrio parahaemolyticus. Strain-to-strain variation in th...
In the present study, Paenibacillus lautus strain BHU3 isolated from landfill soil was evaluated for presence of potential endoglucanases which are first candidate cellulase enzyme system to act on cellulose. In-silico analysis revealed high thermostable can efficiently interact with The most potent and endoglucanase (locus tag id. CPZ30_18280) belonged glycosyl family-5 had interaction energy ...
This paper reports the isolation and identification of chitinase-producing Bacillus from chitin-containing wastes, production of a thermostable and alkaline chitinasese, and enzyme characterization. Bacillus thuringiensis subsp. kurstaki HBK-51 was isolated from soil and was identified. Chitinase was obtained from supernatant of B. thuringiensis HBK-51 strain and showed its optimum activity at ...
In Escherichia coli, growth is limited at elevated temperatures mainly because of the instability of a single enzyme, homoserine o-succinyltransferase (MetA), the first enzyme in the methionine biosynthesis pathway. The metA gene from the thermophile Geobacillus kaustophilus cloned into the E. coli chromosome was found to enhance the growth of the host strain at elevated temperature (44 degrees...
