title: alpha-Mannosidase activity from antibody raised against a glucal antigen.
abstract: Sixty cell lines of monoclonal antibody were raised against a glucal hapten 1. Among them, Ab 405.4 showed alpha-mannosidase activity as kcat = 0.19/day (kcat/kuncat = 110,000). The chemical modification study and pH profile study of this antibody indicated that carboxyl group(s) in the antigen binding site involved in catalytic mechanism.
