Hydrolytic enzymes of the pauaHaliotis iris, a marine gastropod (note).

Abstract

Extracts of the viscera of Haliotis iris (Martyn, 1784) were shown to hydrolyse 2-hydroxy-5-nitrophenyl sulphate at pH 5.5, and the p-nitrophenyl derivatives of α-and β-D-galactose, α-and β-D-mannose, α-L-lucose, β-D-glucuronic acid, β-N-acetyl glucosamine and phosphate at pH 4.0 and 5.5: p-nitrophenyl-β-L-fucose was not hydrolysed.
