[The role of the promoter and leader sequences of extracellular ribonuclease from Bacillus amyloliquefaciens in regulation of enzyme biosynthesis].
It is shown that in the medium rich with inorganic phosphate there is a stimulation of biosynthesis of ribonuclease from B. amyloliquefaciens (barnase) by actinomycin D, while biosynthesis of ribonucleases from B. intermedius (binase) and B. pumilus (KNase Bpu) in these conditions was suppressed. Features of biosynthesis of binase and RNase Bpu, directed by the barnase promoter, and also expression of chimeric gene of RNase Bpu with leader peptide of barnase were investigated. It was established that stimulation of synthesis of extracellular ribonuclease from B. amyloliquefaciens in the presence of actinomycin D was defined by structure of leader sequences.
