3.4.21.B30	dimer	UmuD and the cleavage product UmuD' exist as homodimers. Their subunits can readily exchange to form UmuDD' heterodimers preferentially. Heterodimer formation is an essential step in the degradation pathway of UmuD'	-, 752775	
3.4.21.B30	dimer	UmuD can form homodimers, crosslinking experiments, SDS-PAGE	651628	
3.4.21.B30	dimer	UmuD dimers exchange readily, and the subunits of UmuD2 and UmuD'2 exchange to form the UmuDD' heterodimer. The heterodimer is the preferred but not exclusive protein form, and both the heterodimer and homodimers exhibit slow exchange kinetics, which is further inhibited in the presence of interacting partner DinB	-, 731345
