Domain of unknown function (DUF4922). This family consists of uncharacterized proteins around 310 residues in length and is mainly found in various Bacteroides and Parabacteroides species. Several members are annotated as putative glycosyltransferases, but the specific function of this family is still unknown.

SpoIID/LytB domain. This model describes a domain found typically in two or three proteins per genome in Cyanobacteria and Firmicutes, and sporadically in other genomes. One member is SpoIID of Bacillus subtilis. Another in B. subtilis is the C-terminal half of LytB, encoded immediately upstream of an amidase, the autolysin LytC, to which its N-terminus is homologous. Gene neighborhoods are not well conserved for members of this family, as many, such as SpoIID, are monocistronic. One early modelling-based study suggests a DNA-binding role for SpoIID, but the function of this domain is unknown. [Unknown function, General]

Peptidoglycan hydrolase (amidase) enhancer domain [Cell wall/membrane/envelope biogenesis].

stage II sporulation protein D. Stage II sporulation protein D (SpoIID) is a protein of the endospore formation program in a number of lineages in the Firmicutes (low-GC Gram-positive bacteria). It is expressed in the mother cell compartment, under control of Sigma-E. SpoIID, along with SpoIIM and SpoIIP, is one of three major proteins involved in engulfment of the forespore by the mother cell. [Cellular processes, Sporulation and germination]

Stage II sporulation protein. This domain is found in the stage II sporulation protein SpoIID. SpoIID is necessary for membrane migration as well as for some of the earlier steps in engulfment during bacterial endospore formation. The domain is also found in amidase enhancer proteins. Amidases, like SpoIID, are cell wall hydrolases.
