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

The FACT or facilitator of chromatin transcription complex binds to and alters the properties of nucleosomes. This family represents the N-terminal lobe of the NTD, or N-terminal domain, and acts as a protein-protein interaction domain presumably with partners outside of the FACT complex [1]. Knockout of the whole NTD domain, 1-450 residues in UniProt:P32558, in yeast serves to tender the cells sensitive to DNA replication stress but is not lethal. The C-terminal half of NTD is structurally similar to aminopeptidases, and the most highly conserved surface residues line a cleft equivalent to the aminopeptidase substrate-binding site, family peptidase_M24, Pfam:PF00557 [1].
