CC   -!- FUNCTION: Snake venom serine protease homolog that may act in the
CC       hemostasis system of the prey. {ECO:0000305}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:17559253}.
CC   -!- TISSUE SPECIFICITY: Expressed by the venom gland.
CC       {ECO:0000305|PubMed:17559253}.
CC   -!- SIMILARITY: Belongs to the peptidase S1 family. Snake venom subfamily.
CC       {ECO:0000305}.
CC   -!- CAUTION: Lacks the conserved His residue in position 66 and the
CC       conserved Ser residue in position 205 essential for protease activity.
CC       {ECO:0000305}.
