It exhibits a protease-inhibition activity, and is synthesized by a non-ribosomal peptide synthase in Photorhabdus luminescens. It has a role as a proteasome inhibitor and a bacterial metabolite. It is an azamacrocycle, a lactam, a pentol, a homodetic cyclic peptide and a polyketide. It is functionally related to a syrbactin."}]
