    Protein Summary

    This protein belongs to DUF830 (PF05708) and belongs to the NlpC/P60 superfamily of papain-like cysteine peptidase. This protein represents a variant of NlpC/P60 domain with permuted topology (see Anantharaman and Aravind,  2003). The structure is homologous to 2if6 by New York SG. However, the function (substrate specificity) of the two proteins are likely different. This protein has only a small cavity leads to the catalytic cysteine with a lysine in the pocket, so it could represent a closed form of the enzyme.
