This domain is found in proteins of the membrane-attack complex/ perforin (MACPF) family from Bacteroidetes. These transmembrane pore- forming proteins are organized into three structured domains: an MACPF domain (Pfam:PF01823) and two C-terminal domains, D2 and D3. This entry represents the D2 domain, which adopts an alpha/beta fold [1].	Domain
