CC -!- FUNCTION: Protective protein appears to be essential for both the
CC activity of beta-galactosidase and neuraminidase, it associates with
CC these enzymes and exerts a protective function necessary for their
CC stability and activity. This protein is also a carboxypeptidase and can
CC deamidate tachykinins.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Release of a C-terminal amino acid with broad specificity.;
CC EC=3.4.16.5; Evidence={ECO:0000255|PROSITE-ProRule:PRU10074,
CC ECO:0000255|PROSITE-ProRule:PRU10075};
CC -!- SUBUNIT: Heterodimer of a 32 kDa chain and a 20 kDa chain; disulfide-
CC linked. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Lysosome.
CC -!- SIMILARITY: Belongs to the peptidase S10 family. {ECO:0000305}.
