RT   Oncorhynchus keta.";
RL   Comp. Biochem. Physiol. 117B:445-452(1997).
CC   -!- FUNCTION: Cysteine proteinase that hydrolyzes basic proteins, such as
CC       histones, salmine and clupeine but not milk casein. Shows a preference
CC       for basic residues at P2 and P1 positions.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:9253183}.
CC   -!- TISSUE SPECIFICITY: Found in milt (at protein level).
CC       {ECO:0000269|PubMed:9253183}.
