UCR1 and 2 both participate in the dimer interface. Two orthogonal views of the dimerization domain, with the conserved hydrophobic residues that stabilize the four-helix bundle shown in ball-and-stick representation, and the conserved polar residues that make intrasubunit salt bridges in stick representation.
