Ae. Ferentz et al., DIMERIZATION OF THE UMUD' PROTEIN IN SOLUTION AND ITS IMPLICATIONS FOR REGULATION OF SOS MUTAGENESIS, Nature structural biology, 4(12), 1997, pp. 979-983
NMR spectroscopy has been used to determine that the dimerization inte
rface of UmuD' in solution is not the homodimer interface originally i
nferred from crystallographic data, Instead, it resembles an interface
that had been hypothesized to be involved in filamentation.
