Clan: Peptidase_ME (CL0094)

Summary

LuxS/MPP-like metallohydrolase Add an annotation

All members of this clan are characterised by a HXXEH motif, which is is involved in zinc binding. Furthermore all members adopt an alpha and beta fold. More specifically, there us a four to six stranded antiparallel beta sheet surrounded by five helices. However, LuxS (PFAM:PF02664) is not a peptidase, although its hydrolytic mechanism of catalysis appears to be conserved [1].

This clan contains 4 families and the total number of domains in the clan is 106903. The clan was built by RD Finn.

Structures

For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the MSD group, to allow us to map Pfam domains onto UniProt three-dimensional structures. The table below shows the mapping between the Pfam families in this clan, the corresponding UniProt entries, and the region of the three-dimensional structures that are available for that sequence.
