Two forms of the nymphal thrombin inhibitors (NTI) 3.2 kDaand 14.9 kDa were purified by chromatography on CM-cellulose,Sephacryl S-300 and Sephadex G-50 columns and designated NTI-1 and NTI-2respectively. The NTI-2 turned out to be homogenous monomeric protein in bothnative-PAGE and denatured SDS-PAGE with M(r) value of 14.9 kDaapproximately and its pI(More)
Three superoxide dismutases (EC (TLSOD1, TLSOD2 and TLSOD3) were purified from larvae of the camel tick Hyalomma dromedarii by ammonium sulfate precipitation, ion exchange and gel filtration columns. SDS-PAGE revealed that the subunit molecular masses of the SODs are 40±2 kDa, 67±1.5 kDa and 45±2.6 kDa for TLSOD1, TLSOD2 and TLSOD3, respectively.(More)
Two glutathione peroxidase isoenzymes were purified from 24-day old embryos of the camel tick Hyalomma dromedarii and designated tick embryo glutathione peroxidase 1 and 2 (TEGPx1 and TEGPx2). The purification procedure involved ammonium sulfate precipitation, as well as ion exchange and gel filtration column chromatography. Glutathione peroxidase(More)
Glucose-6-phosphate dehydrogenase from camel liver was purified to homogeneity by ammonium sulfate precipitation and a combination of DEAE-cellulose, Sephacryl S-300 gel filtration, and 2', 5' ADP Sepharose 4B affinity chromatography columns. The specific activity of camel liver G6PD is increased to 1.80438 units/mg proteins with 63-fold purification. It(More)
Glucose-6-phosphate dehydrogenase (G6PD) is a key regulatory enzyme involved in the pentose phosphate pathway. This works represents purification of two buffalo liver glucose-6-phosphate dehydrogenases (BLG6PD1 and BLG6PD2) using combination of ammonium sulfate precipitation and several chromatographic columns. Both enzymes (BLG6PD1 and BLG6PD2) were(More)
