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]

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]

Glycosyltransferase family A (GT-A) includes diverse families of glycosyl transferases with a common GT-A type structural fold. Glycosyltransferases (GTs) are enzymes that synthesize oligosaccharides, polysaccharides, and glycoconjugates by transferring the sugar moiety from an activated nucleotide-sugar donor to an acceptor molecule, which may be a growing oligosaccharide, a lipid, or a protein. Based on the stereochemistry of the donor and acceptor molecules, GTs are classified as either retaining or inverting enzymes. To date, all GT structures adopt one of two possible folds, termed GT-A fold and GT-B fold. This hierarchy includes diverse families of glycosyl transferases with a common GT-A type structural fold, which has two tightly associated beta/alpha/beta domains that tend to form a continuous central sheet of at least eight beta-strands. The majority of the proteins in this superfamily are Glycosyltransferase family 2 (GT-2) proteins. But it also includes families GT-43, GT-6, GT-8, GT13 and GT-7; which are evolutionarily related to GT-2 and share structure similarities.
