A	PF00557	Metallopeptidase family M24 (Peptidase_M24)	Metallopeptidase family M24	This family contains metallopeptidases. It also contains non-peptidase homologues such as the N terminal domain of Spt16 which is a histone H3-H4 binding module [3].	Domain
A	PF21216	Xaa-Pro dipeptidase, N-terminal domain (PepQ_N)	Xaa-Pro dipeptidase, N-terminal domain	This domain is found in Xaa-Pro dipeptidase from Escherichia coli (PepQ), a metalloprotease that catalyse the cleavage of Xaa-Pro dipeptides. This protein is organised into N-terminal (this entry) and C-terminal (usually Pfam:PF00557) domains and ad ...	This domain is found in Xaa-Pro dipeptidase from Escherichia coli (PepQ), a metalloprotease that catalyse the cleavage of Xaa-Pro dipeptides. This protein is organised into N-terminal (this entry) and C-terminal (usually Pfam:PF00557) domains and adopts a dimeric configuration. This domain shows an alpha-beta structure with four helices, one pair flanking each side of the six-stranded mixed beta-sheet [1-5].	Domain
