Density-gradient and chromatographic fraction of leptospiral lipase.
Fractionation of leptospiral lipase by CsCl density gradients and G-200 Sephadex chromatography yielded five active protein peaks. Two were obtained from the density gradients and three from G-200 Sephadex columns. Esterase activity of these fractions was demonstrated by electrophoretic examination. Several protein bands were visible when disc electrophoresis was performed on the respective fra...
متن کاملCharacterization of the leptospiral outer membrane and description of three novel leptospiral membrane proteins.
The outer membrane (OM) of the mammalian pathogen Leptospira kirschneri was isolated in the form of membrane vesicles by alkaline plasmolysis and separated from the protoplasmic cylinder by sucrose density gradient ultracentrifugation. All four components of the alkaline plasmolysis buffer, including 1.0 M NaCl, 27% sucrose (wt/vol), 2 mM EDTA, and 10 mM Tris (pH 9), were required for efficient...
متن کاملFunctional characterization of a chimeric lipase genetically engineered from human lipoprotein lipase and human hepatic lipase.
Lipoprotein lipase (LPL) and hepatic lipase (HL) mediate the hydrolysis of triglycerides and phospholipids present in circulating lipoprotein particles and are essential for normal lipid metabolism. Both enzymes have a similar primary amino acid structure and share requirements for intact catalytic, lipid binding, and heparin binding domains. However, LPL and HL exhibit different substrate spec...
متن کاملLeptospiral Pathogenomics
Leptospirosis, caused by pathogenic spirochetes belonging to the genus Leptospira, is a zoonosis with important impacts on human and animal health worldwide. Research on the mechanisms of Leptospira pathogenesis has been hindered due to slow growth of infectious strains, poor transformability, and a paucity of genetic tools. As a result of second generation sequencing technologies, there has be...
متن کاملLeptospiral Uveitis.
Leptospirosis is widely regarded as the most widespread zoonosis in the world. Systemic leptospirosis is a biphasic illness. Ocular involvement in leptospirosis has been reported to be extremely variable, ranging from 2% to 90%. Ocular involvement is seen both in the systemic bacteraemic phase as well as in the immunological phase. Leptospiral uveitis is a common entity in the tropical countrie...
