Two Major Archaeal Pseudomurein Endoisopeptidases: PeiW and PeiP

Figure 2

Protein sequence alignment of the pseudomurein endoisopeptidases PeiP and PeiW. The picture was generated with the SIM program of the ExPASy proteomics server (http://expasy.org/tools/sim-prot.html). N-terminal direct repeats in the pseudomurein binding repeat domain are shown in green, and the C-terminal catalytic domain is presented in red. The catalytic triad C-H-D is indicated in blue. * indicates identical amino acid residues in PeiP and PeiW.
