This is a family conserved from bacteria to humans. The structure of a member from Bacteroides has been crystallised and modelled onto the luminal region of the human member of the family, the transmembrane glycoprotein N-acetylglucosamine-1-phosphodiester alpha-N-acetylglucosaminidase. There is some conservation of potentially functional residues, implying that in the bacterial members this family acts in some way as a phosphodiester glycosidase [1]. The human protein is also present, so the eukaryotic members are likely to be catalysing the second step in the formation of the mannose 6-phosphate targeting signal on lysosomal enzyme oligosaccharides [2].

Bacterial SPOR domains bind peptidoglycan (PG) and target proteins to the cell division site by binding to denuded glycan strands that lack stem peptides [2]. This 70 residue domain is composed of two 35 residue repeats found in proteins involved in sporulation and cell division such as FtsN, DedD, and CwlM. This domain is involved in binding peptidoglycan [1]. Two tandem repeats fold into a pseudo-2-fold symmetric single-domain structure containing numerous contacts between the repeats [1]. FtsN is an essential cell division protein with a simple bitopic topology, a short N-terminal cytoplasmic segment fused to a large carboxy periplasmic domain through a single transmembrane domain. These repeats lay at the periplasmic C-terminus. FtsN localises to the septum ring complex.
