analysis of one of these mutants showed that lysosomal alpha-mannosidase activity was 18 % of that from wild-type cells , whereas the activities of alpha-mannosidases not of lysosomal origin were similar in the wild type and mutant ( these included both golgi-associated and cytosolic enzymes as well as a novel acid alpha-mannosidase seen only in cells from confluent culture ) .
