The level of resistance to antibiotics of various chemical structure in actinobacteria of the genus Streptomyces is shown to be regulated by Ca2+ ions. The inhibitors of Ca2+/calmodulin and Ca2+/phospholipid-dependent serine/threonine protein kinases (STPK) are found to reduce antibiotic resistance of actinobacteria. The effect of Ca2+-dependent(More)
The relationship between mutagenic activity and chemical structure was studied for 54 polycyclic compounds using two approaches: multiple linear regression analysis and artificial neural networks. Structural fragments, quantum chemical indices, and hydrophobicity (octanol–water partition coefficient) were used as descriptors (properties of the molecules(More)
A new method of the efficiency assessment of testing mutagenicity chemical pollutants is proposed. The method is based on the selective information criterion and allows one to compare the prognostic significance of results obtained in both individual tests and test batteries. The efficiency of mutagen detection in mammals was estimated in Ames' test, the in(More)
Programmed death (PD) of the mycelium of Streptomyces lividans, namely, its delayed lysis in response to treatment with indolylmaleimide derivatives, which inhibit actinobacterial serine/threonine protein kinases (STPK), is described. Delayed lysis of mycelial cell was accompanied by DNA damage similar to PD in differentiating S. lividans mycelium.(More)
