Active site of bee venom phospholipase A2: the role of histidine-34, aspartate-64 and tyrosine-87.

R R Annand et al.

Biochemistry, 35(14), 4591-4601 (1996-04-09)

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

Solvatochromic Study of Two Carbanion Monosubstituted 4-Tolyl-1,2,4-triazol-1-ium Phenacylids in Binary Hydroxyl Solvent Mixtures.

Dana Ortansa Dorohoi et al.

Molecules (Basel, Switzerland), 26(13) (2021-07-03)

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

Use of an imperfect neutral diluent and outer vesicle layer scooting mode hydrolysis to analyze the interfacial kinetics, inhibition, and substrate preferences of bee venom phospholipase A2.

B Z Yu et al.

Biochemistry, 36(13), 3870-3881 (1997-04-01)

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
