'''Staphostatins resemble lipocalins, not cystatins in fold.'''
+
== Function ==
-
 
+
[https://www.uniprot.org/uniprot/SSPC_STAAW SSPC_STAAW] Specifically inhibits the cysteine protease staphopain B (SspB) by blocking the active site of the enzyme. Probably required to protect cytoplasmic proteins from being degraded by prematurely activated/folded prostaphopain B. Also involved in growth capacity, viability and bacterial morphology (By similarity).

==Overview==
+
</StructureSection>
-
Staphostatins are the endogenous inhibitors of the major secreted cysteine proteases of Staphylococcus aureus, the staphopains. Here, we present the 1.4 A crystal structure of staphostatin B and show that the fold can be described as a fully closed, highly sheared eight-stranded beta-barrel. Thus, staphostatin B is related to beta-barrel domains that are involved in the inhibition or regulation of proteases of various catalytic types and to the superfamily of lipocalins/cytosolic fatty acid binding proteins. Unexpectedly for a cysteine protease inhibitor, staphostatin B is not significantly similar to cystatins.
