Molecular cloning and expression of cellulase genes of alkalophilic Bacillus sp. strain N-4 in Escherichia coli.
The genes for cellulases of alkalophilic Bacillus sp. strain N-4 were cloned in Escherichia coli with pBR322. Plasmids pNK1 and pNK2 were isolated from the transformants producing carboxymethyl cellulase, and the carboxymethyl cellulase genes cloned were in 2.0- and 2.8-kilobase-pair HindIII fragments, respectively. On the DNA level, the pNK1 fragment had a different restriction map from that o...
متن کاملCloning and Expression of Mannheimia haemolytica PlpE Gene in Escherichia coli and its Immunogenicity Assessment
Mannheimia haemolytica is responsible for considerable economic losses to cattle, sheep, and goat industries in many parts of the world. This bacterium isone of the causative agents of shipping fever in cattle. Current vaccines against M. haemolytica are moderately efficacious since they do not provide complete protection against the disease. Production of a...
متن کاملMolecular cloning and characterization of an alkalophilic Bacillus sp. C125 gene homologous to Bacillus subtilis sec Y.
A 1.8 kb HindIII DNA fragment containing the secY gene of alkalophilic Bacillus sp. C125 has been cloned into plasmid pUC119 using the B. subtilis secY gene as a probe. The complete nucleotide sequence of the cloned DNA indicated that it contained one complete ORF and parts of two other ORFs. The similarity of these ORFs to the sequences of the B. subtilis proteins indicated that they were the ...
متن کاملIsolation and cloning of the endoglucanase gene from Bacillus pumilus and its expression in Deinococcus radiodurans
With the aim of engineering a strain of bacteria that could be used for bioremediation of cellulosic waste in radioactive environments, the gene for the secreted endoglucanase enzyme of Bacillus pumilis was decided to be cloned into the radiotolerant bacterium, Deinococcus radiodurans. The endoglucanase gene from B. pumilus was PCR amplified and cloned into Escherichiacoli DH5α using a pDrive v...
متن کاملCloning and expression in Escherichia coli of chromosomal mercury resistance genes from a Bacillus sp.
A 7.9-kilobase (kb) chromosomal fragment was cloned from a mercury-resistant Bacillus sp. In Escherichia coli, in the presence of a second plasmid carrying functional transport genes, resistance to HgCl2 and to phenylmercury acetate (PMA) was expressed. Shortening the cloned fragment to 3.8 kb abolished resistance to PMA but not to HgCl2. In Bacillus subtilis, the 3.8-kb fragment produced mercu...
