Abstract
Pomacea canaliculata alpha-mannosidase (260 kDa), composed of at least two isoforms with different pI, was partially purified. The activity was maximu m at pH 4 and unaltered after incubation at 60 degrees C for 60 min. ZnCl2, CaCl2, NaCl, and SH-reagents increased the activity, while MnCl2 and EDTA inhibited it. The enzyme catalyzed the hydrolysis of alpha 1-2, alpha 1-3, and alpha 1-6 mannosidic linkages.
