Extracellular Cholesterol Oxidase from Rhodococcus sp.: Isolation and Molecular Characterization
Background: Cholesterol oxidase (CHO) has various clinical and industrial applications. Recently, microbial CHO have received a great attention for their wide usage in medicine. Here, taxonomic characterizations of isolated strain from soil, optimization of the conditions for CHO production and biochemical characterizations of produced CHO enzyme were described. Finally, CHO gene was cloned int...
متن کاملPartial Purification and Characterisation of Polyphenol Oxidase from Tomatoes (Solanum Lycopersicum)
Polyphenol oxidase (PPO) from tomatoes was extracted and partially purified through (NH4)2SO4 precipitation, dialysis and ion exchange chromatography. The activity of polyphenol oxidase was investigated in solanum lycopersicum. Spectrophotometric method was used to assay the enzyme activity and the kinetic constants - maximum enzyme velocity (Vmax) and Michealis - Menten constant (Km). Of the ...

متن کاملPurification and characterization of extracellular Pseudomonas aeruginosa urate oxidase enzyme.
Urate oxidase (uricase) was isolated and purified from Pseudomonas aeruginosa to apparent homogeneity using ammonium sulphate precipitation followed by ion exchange and gel filtration chromatography. The specific activity of the purified uricase enzyme was found to be 636.36 with the use of uric acid as a substrate. The purified uricase enzyme is a monomeric protein with molecular weight of 64 ...
