Proteasomes are the main cytosolic proteases responsible for generating peptides for antigen processing and presentation in the MHC (major histocompatibility complex) class-I pathway. Purified 20S and 26S proteasomes have been widely used to study both specificity and efficiency of antigen
Cryptococcus neoformans is a human-pathogenic basidiomycete that commonly infects HIV/AIDS patients to cause meningoencephalitis (7, 19). C. neoformans grows as a budding yeast during vegetative growth or as hyphae during sexual reproduction. Pseudohyphal growth of C. neoformans has been observed
Fibrinolytic peptidase of Bacillus thuringiensis IMV B-7324 was isolated by ammonium sulfate fractionation, gel-filtration and ion exchange chromatography on TSK-gels--Toyopearl HW-55 and DEAE 650 (M). Fibrinolytic activity of the purified enzyme was 87.9 U/mg of protein that was 19.9 times

Factors influencing poly(3-hydroxybutyrate) P(3HB) production by Cupriavidus necator CCUG52238(T) utilizing oil palm frond (OPF) juice were clarified in this study. Effects of initial medium pH, agitation speed, and ammonium sulfate (NH(4))(2)SO(4) concentration on the production of P(3HB) were investigated in
A serine protease was purified 6.9-fold from the leaves of Thespesia populnea using ammonium sulfate fractionation followed by CM-cellulose and Sephadex G-100 chromatography. The purified enzyme was named populnein and was characterized. It was made up of a single polypeptide
