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 کاملExpression and Secretion of Cyan Fluorescent Protein (CFP) in B. subtilis using the Chitinase Promoter from Bacillus pumilus SG2
Background: Improved cyan fluorescent protein (ICFP) is a monochromic, green fluorescent protein (GFP) derivative produced by Aequorea macrodactyla in a process similar to GFP. This protein has strong absorption spectra at wavelengths 426-446 nm. ICFP can be used in cell, organelle or intracellular protein labeling, investigating the protein-protein interactions as well as assessing the promote...
متن کاملAn alternative bacterial expression system using Bacillus pumilus SG2 chitinase promoter
Background: Chitin is an abundant natural polysaccharide found in fungi, algae, and exoskeleton of insects. Several bacterial species are capable of utilizing chitin as their carbon source. These bacteria produce chitinases for degradation of chitin into N-acetyl-D-glucosamine. So far, regulation of the chitinase encoding genes has been studied in different bacterial species. Among Bacillus spe...
متن کاملTwo-component regulatory proteins ResD-ResE are required for transcriptional activation of fnr upon oxygen limitation in Bacillus subtilis.
Bacillus subtilis can grow anaerobically in the presence of nitrate as a terminal electron acceptor. The two component regulatory proteins, ResD and ResE, and an anaerobic gene regulator, FNR, were previously shown to be indispensable for nitrate respiration in B. subtilis. Unlike Escherichia coli fnr, B. subtilis fnr transcription was shown to be highly induced by oxygen limitation. fnr is tra...
متن کاملTranscriptional activation of the Bacillus subtilis spoIIG promoter by the response regulator Spo0A is independent of the C-terminal domain of the RNA polymerase alpha subunit.
In vitro transcription from the spoIIG promoter by Bacillus subtilis RNA polymerase reconstituted with wild-type alpha subunits and with C-terminal deletion mutants of the alpha subunit was equally stimulated by the response regulator Spo0A. Some differences in the structure of open complexes formed by RNA polymerase containing alpha subunit mutants were noted, although the wild-type and mutant...
متن کاملA region in the Bacillus subtilis transcription factor Spo0A that is important for spoIIG promoter activation.
Spo0A is a DNA binding protein in Bacillus subtilis required for the activation of spoIIG and other promoters at the onset of endospore formation. Activation of some of these promoters may involve interaction of Spo0A and the sigmaA subunit of RNA polymerase. Previous studies identified two single-amino-acid substitutions in sigmaA, K356E and H359R, that specifically impaired Spo0A-dependent tr...
