MOLECULAR 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 کاملDifferential gene expression in Bacillus subtilis
1 Sporulation in Bacillus subtilis serves as a paradigm for the development of two different cell types (mother cell and prespore) from a single cell. The mechanism by which the two different developmental programs are initiated has been much studied but is not well understood. With the help of existing and new experimental results, a mathematical model has been developed that reproduces all pu...
متن کاملOrganized cell swimming motions in Bacillus subtilis colonies: patterns of short-lived whirls and jets.
The swimming motions of cells within Bacillus subtilis colonies, as well as the associated fluid flows, were analyzed from video films produced during colony growth and expansion on wet agar surfaces. Individual cells in very wet dense populations moved at rates between 76 and 116 microm/s. Swimming cells were organized into patterns of whirls, each approximately 1,000 microm2, and jets of abou...
متن کاملNoise in gene expression determines cell fate in Bacillus subtilis.
Random cell-to-cell variations in gene expression within an isogenic population can lead to transitions between alternative states of gene expression. Little is known about how these variations (noise) in natural systems affect such transitions. In Bacillus subtilis, noise in ComK, the protein that regulates competence for DNA uptake, is thought to cause cells to transition to the competent sta...
متن کاملAdaptive gene expression in Bacillus subtilis strains deleted for tetL.
The growth properties of a new panel of Bacillus subtilis tetL deletion strains and of a derivative set of strains in which tetL is restored to the chromosome support earlier indications that deletion of tetL results in a range of phenotypes that are unrelated to tetracycline resistance. These phenotypes were not reversed by restoration of a tetL gene to its native locus and were hypothesized t...
