In bee venom phospholipase A2, histidine-34 probably functions as a Brønsted base to deprotonate the attacking water. Aspartate-64 and tyrosine-87 form a hydrogen bonding network with histidine-34. We have prepared mutants at these positions and studied their kinetic properties. The

The alkylating agent 2-bromo-4'-nitroacetophenone (BrNAP) binds covalently to each of 10 isozymes of purified rat liver microsomal cytochrome P-450 (P-450a-P-450j) but substantially inhibits the catalytic activity of only cytochrome P-450c. Regardless of pH, incubation time, presence of detergents, or concentration

Two 4-tolyl-1,2,4-triazol-1-ium methylids, namely 4-tolyl-1,2,4-triazol-1-ium-phenacylid and 4-tolyl-1,2,4-triazol-1-ium-4'-nitro-phenacylid, are studied from solvatochromic point of view in binary solvent mixtures of water with ethanol and water with methanol. The contributions (expressed in percent) of the universal and specific interactions are separated from

Interfacial catalytic constants for bee venom phospholipase A2 (bvPLA2) have been obtained for its action on vesicles of the anionic phospholipid 1,2-dimyristoylphosphatidylmethanol (DMPM) in the highly processive scooting mode. Spectroscopic measurements which directly measure transbilayer movement of membrane components show

A new highly selective and visible colorimetric fluorescent probe (probe 1) was developed to detect hydrazine (N2H4) concentration in real water samples. As different concentrations of N2H4 were added, the color of the probe solution was graded gradually from colorless
