Two distinct glutathione transferases from the liver of adult Tilapia zilli were identified and purified to apparent homogeneity by ion-exchange chromatography on DEAE-cellulose and by gel filtration on Sephadex G-150. These major GST forms labeled tzGST1 and tzGST2 accounted for approximately 42% of the activity detectable with 1-chloro-2,4-dinitrobenzene(More)
Thirty-five Bacillus isolates were obtained from traditionally fermented locust bean ( ̈iru ̈) in Akure, South-western part of Nigeria. Twelve of the bacillus isolates were identified as Bacillus licheniformis, twentyone as Bacillus subtilis and two as Bacillus cereus according to physiological and biochemical properties. The B. licheniformis isolates were(More)
Ethanol extracts of Tithonia diversifolia, Cyperus rotundus and Hyptis suaveloensis have earlier been reported to have insecticidal activity against storage bruchid (Callosbrochus maculatus) reared on cowpea (Vigna unguiculata). Here, antioxidant capacities of the ethanol extracts of these plants were evaluated by determining their effects on DPPH radical(More)
Protein carbamylation is of great concern both in vivo and in vitro. Here, we report the first structural characterization of a protein carbamylated at the N-terminal proline. The unexpected carbamylation of the α-amino group of the least reactive codified amino acid has been detected in high-resolution electron density maps of a new crystal form of the(More)
This study was conducted to investigate the metabolic defensive mechanism in the larvae of African palm weevil (Rynchophorus phoenicis) administered with dichlorvos (2,2-dichlorovinyl dimethylphosphate) solution. Bioassay experiment with dichlorvos was conducted on the larva and glutathione-utilizing enzyme activities were determined in the major organs:(More)
