This family of proteins is functionally uncharacterised. This family of proteins is found in prokaryotes. Advanced homology-detection methods supported with superfamily-wide domain architecture and horizontal gene transfer analyses s have established this family to be a member of the PD-(D/E)XK superfamily.
