This entry represents domain 4 from the C-terminal lobe of PQQ synthase PqqF, a protein required for coenzyme pyrroloquinoline quinone (PQQ) biosynthesis. It consists of four structurally similar domains organised in N-terminal (domain 1 represented in Pfam: PF00675 and domain 2 in Pfam:PF22454) and C-terminal (domain 3 and domain 4) lobes [1]. This domain is also found in other Peptidase M16 members, such as Nardilysin and insulin degrading enzymes from human.	Domain
