transferase 2, rSAM/selenodomain-associated. This enzyme may transfer a nucleotide, or it sugar moiety, as part of a biosynthetic pathway. Other proposed members of the pathway include another transferase (TIGR04282), a phosphoesterase, and a radical SAM enzyme (TIGR04167) whose C-terminal domain (pfam12345) frequently contains a selenocysteine.

GT_2_like_a represents a glycosyltransferase family-2 subfamily with unknown function. Glycosyltransferase family 2 (GT-2) subfamily of unknown function. GT-2 includes diverse families of glycosyltransferases 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. These are enzymes that catalyze the transfer of sugar moieties from activated donor molecules to specific acceptor molecules, forming glycosidic bonds. Glycosyltransferases have been classified into more than 90 distinct sequence based families.
transferase 1, rSAM/selenodomain-associated. Members of this protein family show strongly correlated phylogenetic distribution, and in most cases co-clustering, with an unusual radical SAM enzyme (TIGR04167) whose C-terminal pfam12345 domain often contains a selenocysteine residue. Other members of the conserved gene neighborhood include another putative glycosyltransferase, an alkylhydroperoxidase family protein (TIGR04169), and a phosphoesterase family protein (TIGR04168). The cassette is likely to be biosynthetic but its exact function is unknown. [Unknown function, Enzymes of unknown specificity]
Uncharacterized protein conserved in bacteria (DUF2064). This family has structural similarity to proteins in the nucleotide-diphospho-sugar transferases superfamily. The similarity suggests that it is an enzyme with a sugar substrate.
