Abstract
1. Goat kidney beta-mannosidase was purified 8500-fold to a specific activity of 65,000 nmol/h per mg of protein with a 6% yield by using multiple steps including cation-exchange and anion-exchange fast protein liquid chromatography. This is the first description of a highly purified preparation from goat tissue; however, it was not homogeneous, as judged by silver-stained SDS/polyacrylamide-gel electrophoresis. 2. The enzyme exhibited microheterogeneity when analysed by isoelectric focusing (pI 5.5-6.5). 3. Purified beta-mannosidase hydrolysed the terminal beta-(1→4)-linkage of oligosaccharides that accumulate in beta-mannosidosis.
