An intracellularly produced constitutive heparinase was isolated from the periplasmic space of Acinetobacter calcoaceticus by freeze fracturing and purified 51.2-fold by ion exchange and gel filtration chromatography. Specific activity of the purified enzyme was found to be 41 IU/mug protein with a 120000Da molecular mass. The enzyme activity was maximum at(More)
A heparinase-producing fungus was isolated, and the strain was taxonomically characterized as Aspergillus flavus by morphophysiological and 26S rRNA gene homology studies. The culture produced intracellular heparinase enzyme, which was purified 40.5-fold by DEAE-Sephadex A-50, CM-Sephadex C-50, and Sephadex G-100 column chromatography. Specific activity of(More)
Heparin/heparan sulphate glycosaminoglycans (HSGAGs) are composed of linear chains of 20–100 disaccharide units of N-acetylated d-glucosamine α (1–4) linked to glucuronic acid. HSGAGs are widely distributed on the cell surface and extracellular cell matrix of virtually every mammalian cell type and play critical role in regulating numerous functions of(More)
A microbial isolate, characterized as Streptomyces sp. (MTCC 6819), produced antifungal metabolite intracellularly and antibacterial metabolite extracellularly under submerged fermentation conditions. This Gram-positive bacterium showed broad antimicrobial activity spectra against both Gram-positive and Gram-negative bacteria. The minimum inhibitory(More)
AIMS Aim of the study was to develop a medium for optimal heparinase production with a strain of Aspergillus flavus (MTCC-8654) by using a multidimensional statistical approach. METHODS AND RESULTS Statistical optimization of intracellular heparinase production by A. flavus, a new isolate, was investigated. Plackett-Burman design was used to evaluate the(More)
APOBEC3G (A3G) protein has antiviral activity against HIV and other pathogenic retroviruses. A3G has two domains: a catalytic C-terminal domain (CTD) that deaminates cytidine, and a N-terminal domain (NTD) that binds to ssDNA. Although abundant information exists about the biological activities of A3G protein, the interplay between sequence specific(More)
Antimicrobial activities of twenty bacterial strains isolated from ten different stressed agro-ecological niches of Eastern Uttar Pradesh, India were evaluated against bacteria, yeasts and molds. Eleven isolates showing strong antimicrobial activities were characterized. Eight antifungal compounds were purified and partially characterized by Ultra-Violet(More)
Heparinases are microbially produced enzymes that degrade heparins, the sulfated glycosaminoglycans, to generate low-molecular-weight heparins (LMWHs). A heparinase-producing fungus, Aspergillus oryzae, was isolated from soil sample. The fungus produced heparinase, both extracellularly and intracellularly, in its late log phase of growth. Heparinase(More)
