Differential effect of hydroxyurea on the replication of plasmid and chromosomal DNA in Bacillus subtilis.
The replication in Bacillus subtilis of the staphylococcal R plasmids pE194, pBD15, pUB110, pSA0501, and pSA2100 has been studied in the presence of hydroxyurea. In all cases, an enrichment for covalently closed circular DNA compared with chromosomal DNA was observed. In this respect, hydroxyurea mimics the effect previously observed with pUB110, using strains carrying the conditional mutation ...
متن کاملMolecular cloning with bifunctional plasmid vectors in Bacillus subtilis: isolation of a spontaneous mutant of Bacillus subtilis with enhanced transformability for Escherichia coli-propagated chimeric plasmid DNA.
Hybrid plasmid DNA cloned in Escherichia coli undergoes deletions when returned to competent Bacillus subtilis, even in defined restriction and modification mutants of strain 168. We have isolated a mutant of B. subtilis MI112 which is stably transformed at high frequency by chimeric plasmid DNA propagated in E. coli.
متن کاملTransformation of Bacillus subtilis by single-stranded plasmid DNA.
The single-stranded form of a pE194-based plasmid transformed Bacillus subtilis protoplasts at least as efficiently as did the double-stranded plasmid, but the single-stranded form did not detectably transform B. subtilis competent cells.
متن کاملMOLECULAR CLONING AND EVALUATION OF WILD PROMOTER IN EXPRESSION OF BACILLUS SPHAERICUS PHENYLALANINE DEHYDROGENASE GENE IN BACILLUS SUBTILIS CELLS
To evaluate the role of wild promoter of L-phenylalanine dehydrogenase (PheDH) gene, referred to as pdh, from Bacillus sphaericus in expression, cloning of pdh gene in Bacillus subtilis was performed. The whole pdh gene was cloned in pHY300PLK shuttle vector and amplified, construct (pHYDH) then transformed in B. subtilis ISW1214 and E. coli JM109. The pdh endogenous promoter presented no effec...
متن کاملIn vitro elaboration Mutagenesis and cloning of the PA gene in Bacillus subtilis
Background: The immune antigen of Bacillus anthracis is a protein that can attach to the surface receptor of all human cells. At the surface of cancer cells, there is a receptor that activates the uPA (Urokinase plasminogen) that do not exist in normal human cells. Objectives: The aim of this study was changing the location of the attachment of the PA gene by a dir...
