Comments Although strongly related to XerD, it constitutes a distinct protein family. In contrast to the classic XerD protein, it does not contain the Arg-His-Arg-His (R-H-R-H) sandwich residues that are clustered with the Tyr active site. It also lacks the C-terminal region which is known to mediate the interaction with XerC. It is therefore unknown whether it has tyrosine recombinase activity or acts as a regulator.
