CC   -!- FUNCTION: Potent plasminogen activator that converts plasminogen into
CC       plasmin. It forms a 1:1 complex with plasmin, which in turn activates
CC       other plasminogen molecules (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the staphylokinase family. {ECO:0000305}.
