Comparative Studies on Retroviral Proteases: Substrate Specificity
Exogenous retroviruses are subclassified into seven genera and include viruses that cause diseases in humans. The viral Gag and Gag-Pro-Pol polyproteins are processed by the retroviral protease in the last stage of replication and inhibitors of the HIV-1 protease are widely used in AIDS therapy. Resistant mutations occur in response to the drug therapy introducing residues that are frequently f...
متن کاملStudies on the Biosynthesis of Extracellular Proteases by Bacteria
Apparently the extracellular protease of S. marcescens is present in protein- or protein derivative-free media only when the conditions favor an abundant growth and bacterial conglomerates are formed, which possibly could be explained by assuming that the proteins of dead bacteria or proteic metabolic products act as inducers of protease formation. Dilute solutions of gelatin induce the product...
متن کاملStudies on Keratinolytic Activity of Alkaline Proteases from Halophilic Bacteria
Alkaline proteases producing halophilic bacteria isolated from Sambar Lake, Rajasthan were investigated for keratinolytic activity. The aim of this study was to optimize culture conditions for maximum enzyme production as well as characterization of proteases with keratinolytic action. Casein was used as sole carbon and nitrogen source for alkaline protease production at 37°C and 150 rpm. Highe...
متن کاملStructural studies of chromatin by using proteases.
Chromatin structure The repeating unit of chromatin, the nucleosome, contains typically about 200 bp of DNA of which 146bp are externally wound in I .75 superhelical left-handed superturns around an octamer of the core histones. This octamer consists of two copies each of H2A, H2B, H3 and H4 histones and together with its DNA is termed the core particle. It has a diameter of 1l.Onm and a thickn...
متن کاملStructural and biochemical studies of retroviral proteases.
Retroviral proteases form a unique subclass of the family of aspartic proteases. These homodimeric enzymes from a number of viral sources have by now been extensively characterized, both structurally and biochemically. The importance of such knowledge to the development of new drugs against AIDS has been, to a large extent, the driving force behind this progress. High-resolution structures are ...
