Usually indicative of serine protease inhibitors. However, kazal-like domains are also seen in the extracellular part of agrins, which are not known to be protease inhibitors. Kazal domains often occur in tandem arrays. Small alpha+beta fold containing three disulphides. Alignment also includes a single domain from transporters in the OATP/PGT family Swiss:P46721.
Serine protease B extracted from Streptomyces griseus shows similar active site architecture to the well characterised family of human serine proteases and displays trypsin like specificity for its peptide substrates. It has proved especially useful in analysing the effect of peptide inhibitors such as turkey ovomucoid inhibitor.
