HIGHLIGHTS Boceprevir is a potential therapeutic that targets the main protease of SARS-CoV-2. Mutations change inhibitory binding pattern in catalytic domain protease. SARS-CoV-2 cause decrease boceprevir affinity.

In line with elds of theoretical computer science and biology that study Boolean automata networks often seen as models of regulation networks, we present some results concerning the dynamics of networks whose underlying interaction graphs are circuits, that is Boolean automata circuits. In the context of biological regulation, former studies have highlighted the importance of circuits on the a...

Previous investigations in this laboratory have dealt with the striking effect of glucose on the induced biosynthesis of three enzyme systems in Aerobacter aerogenes (Magasanik, 1955; Neidhardt and Magasanik, 1956a). During the course of these studies it was found that glucose is not the only substance whose inclusion in a growth medium restricts induced enzyme biosynthesis, although it is uniq...

the goal of this research was to isolate and identify the thermostable alkaline protease producing bacteria among several native iranian microorganisms. at the end of screening program, a bacillus subtilis bp-36 strain producing thermophilic alkaline protease was isolated from a hot spring in ardebil province. the target enzyme was purified using a one-step aqueous two-phase systems (atps) prot...

objective: investigations were carried out to isolate bacteria from saline-alkali soils and determined optimized alkaline protease activity and stability produced by a wild strain of bacillus sp. in submerged fermentation (smf). methods: optimum temperature for enzyme activity in the crude extract was 40 ◦c at a ph between 8.0 and 9.0. the studies on ph stability showed that the enzyme was stab...

background and objectives: psychrotrophic bacteria can produce enzymes at low temperatures; this provides a wide biotechnological potential, and offers numerous economical advantages over the use of mesophilic bacteria. in this study, extracellular protease production by psychrotrophic rheinheimera sp. (km459533) was optimized by the response surface methodology. materials and methods: the cult...

background and objectives: bacteria, most prevalently the pseudomonas species possess high capacity to utilize and de- grade petroleum hydrocarbons and are classified as the hydrocarbonoclastic microorganisms. many species of the genus pseudomonas are notorious for their aerobic degradation capacity, extracellular enzyme production and are metabolically versatile organisms capable of utilizing ...

dyslipidemia has become a common problem in human immunodeficiency virus (hiv) disease, especially in patients on combination antiretroviral therapy. we investigated the prevalence of and factors associated with dyslipidemia in hiv-infected patients in iran. in this cross-sectional study, 190 hiv positive patients who referring to behavioral disease consulting centers (shemiranat, varamin) and ...

The reversible inhibition of protein synthesis at the 75-95 % level in the early zygote of Fundulus results in a specific series of developmental failures dependent upon the times of inhibitor pulse initiation. The severity of the morphogenetic failure is inversely related to the time of initiation and directly to the length of the pulse. The defects reflect the time dependent serial order of e...

A study of the relative effectiveness of some eighteen natural and synthetically modified cytochalasins on the uptake of glucose by the Gram-positive bacterium Arthrobacter sialophilus showed that cytochalasins B, C or D and aspochalasins A, C or D were inactive natural congeners. The presence of an alpha,beta-unsaturated carbonyl group in the macrolide moiety of these compounds with appropriat...
