sspA

Gene
sspA
Protein
Glutamyl endopeptidase
Organism
Staphylococcus aureus (strain MRSA252)
Length
357 amino acids
Function
Preferentially cleaves peptide bonds on the carboxyl-terminal side of aspartate and glutamate. Along with other extracellular proteases it is involved in colonization and infection of human tissues. Required for proteolytic maturation of thiol protease SspB and inactivation of SspC, an inhibitor of SspB. It is the most important protease for degradation of fibronectin-binding protein (FnBP) and surface protein A, which are involved in adherence to host cells. May also protect bacteria against host defense mechanism by cleaving the immunoglobulin classes IgG, IgA and IgM. May be involved in the stability of secreted lipases (By similarity).
Similarity
Belongs to the peptidase S1B family.

Organism
Bacillus subtilis (strain 168)
Length

Function
SASP are bound to spore DNA. They are double-stranded DNA-binding proteins that cause DNA to change to an a-like conformation. They protect the DNA backbone from chemical and enzymatic cleavage and are thus involved in dormant spore's high resistance to UV light.
Similarity
Belongs to the alpha/beta-type SASP family.
