CC   -!- FUNCTION: Cysteine protease able to degrade elastin (By
CC       similarity).
CC   -!- CATALYTIC ACTIVITY: Broad endopeptidase action on proteins
CC       including elastin, but rather limited hydrolysis of small-molecule
CC       substrates. Assays are conveniently made with hemoglobin, casein
CC       or Z-Phe-Arg-NHMec as substrate.
CC   -!- ENZYME REGULATION: Prematurely activated/folded staphopain A is
CC       inhibited by staphostatin A (scpB), which is probably required to
CC       protect staphylococcal cytoplasmic proteins from degradation by
CC       scpA (By similarity).
CC   -!- SUBUNIT: In the cytoplasm, prematurely activated/folded scpA forms
CC       a stable non-covalent complex with scpB (By similarity).
CC   -!- SUBCELLULAR LOCATION: Secreted (By similarity).
CC   -!- PTM: Cleavage leads to the activation of scpA probably by an auto-
CC       catalytic manner (By similarity).
CC   -!- MISCELLANEOUS: The catalytic maturation of scpA appears to reside
CC       outside the cascade of activation started by the metalloprotease
CC       aureolysin (aur) (By similarity).
CC   -!- SIMILARITY: Belongs to the peptidase C47 family.
