This domain is currently only found in a small set of S. coelicolor secreted proteins. There are four conserved cysteines that probably form two disulphide bonds. Proteins 2SCK31.15C (Swiss:Q9ADK5) and SCO3675 (Swiss:Q9X8V7) also have probable beta-propellers at their C-termini. This family includes Swiss:P01077 a known peptidase inhibitor of known structure. This protein has a crystallin like fold Pfam:PF00030 and is distantly related by sequence. It is not known whether other members of this family are peptidase inhibitors.	Domain
