    Ligand Information



    Protein Summary

    A hypothetical protein consists of three domains: N-terminal and C-terminal PDZ domains, and a middle DUF4136 domain.

    The overall shape of the molecule is similar to DegP, which instead contains a protease and two N-terminal PDZ domains. This protein does not contain a protease domain, but an DUF4136 domain. Based on the domain organization, we speculate that this protein may be a periplasmic chaperone involved in a secretion process.
