Abstract: The kinetic properties of β-glucosidases from three tropical plant species, Manihot glaziovii, Passiflora foetida and Prunus polystachya, were studied. Differences were seen in their ability to hydrolyse some of the p-nitrophenyl-β-d-glycosides and in other kinetic parameters such as activation energy, affinity for p-nitrophenyl-β-d-glucoside and p-nitrophenyl-β-d-fucoside, and inhibition by glucono-1,5-lactone and imidazole. The results further suggested that enzyme catalysis might involve the participation of both acid and basic amino acid residues in the enzyme active site and a requirement for planar half-chair conformation of the reactive intermediate. © 1994.
