The effect of Bacillus intermedius RNAase on vegetative cells and spores of siliceons bacteria Bacillus mucilaginosus was investigated. It is shown that the enzyme stimulates the growth of vegetative cells of B. mucilaginosus at a concentration of 10 mkg/ml and promotes germination of spores at a 1000-fold lesser concentration (0.1 mkg/ml). The spores at stages of activation and initiation appear to be most susceptible to the enzyme action. The effect of RNAase on B. mucilaginosus multiplication correlates with intensification of bacterial leaching of bauxites.

Structural insights in interactions between RNase from Bacillus Intermedius and rhamnogalacturonan I from potato.

Carbohydr Polym

Kazan Institute of Biochemistry and Biophysics, FRC Kazan Scientific Center of RAS, 420111, Lobachevsky str. 2/31, Kazan, Russian Federation.

Being biocompatible and biodegradable polymers, polysaccharides present a perspective material for drug delivery systems. This study aimed at unraveling the molecular details of interactions between rhamnogalacturonan I, brunched with galactan side chains, and RNase from Bacillus Intermedius, binase. FTIR- and NMR-spectroscopic analyses showed that binase interacts with side chains of the polysaccharide.

The cytotoxic effects of Bacillus intermedius RNase (binase) towards ovarian cancer cells (SKOV3 and OVCAR5) were studied in comparison to normal ovarian epithelial cells (HOSE1 and HOSE2). Binase decreased viability and induced the selective apoptosis of ovarian cancer cells. The apoptosis rate was 50% in SKOV3 and 48% in OVCAR5 cells after 24 h of binase treatment (50 μg/ml).

Binase-like guanyl-preferring ribonucleases are new members of Bacillus PhoP regulon.

Microbiol Res

January 2015

Institute for Cell and Molecular Biosciences, University of Newcastle upon Tyne, Newcastle upon Tyne NE2 4HH, United Kingdom. Electronic address:

Extracellular low-molecular weight guanyl-preferring ribonucleases (LMW RNases) of Bacillus sp. comprise a group of hydrolytic enzymes that share highly similar structural and catalytic characteristics with barnase, a ribonuclease from Bacillus amyloliquefaciens, and binase, a ribonuclease from Bacillus intermedius. Although the physical-chemical and catalytic properties of Bacillus guanyl-preferring ribonucleases are very similar, there is considerably more variation in the environmental conditions that lead to the induction of the genes encoding these RNases.

The successful application of exogenous ribonucleases of different origin to suppress tumor growth allows one to consider them as perspective therapeutics for treatment of oncological diseases. An important aspect of the success of an anti-cancer drug is low hepatotoxicity, which will reduce, if not eliminate entirely the undesirable side effects of treatment. Previously we have shown that ribonuclease from Bacillus intermedius (binase) exhibits high antitumor and antimetastatic activity in tumor models of different histological origin.

Antiviral Activity of Binase against the Pandemic Influenza A (H1N1) Virus.

Acta Naturae

October 2013

Institute of Fundamental Medicine and Biology, Kazan (Volga Region) Federal University, Kremlyovskaya Str., 18, Kazan, Russia, 420008.

The lack of effective antiviral drugs restricts the control of the dangerous RNA-containing influenza A (H1N1) virus. Extracellular ribonuclease of Bacilli (binase) was shown to manifest antiviral activity during single- and multi-cycle viral replication in the range of concentrations non-toxic to epithelial cells and 0.01-0.
