Abstract excerpt
In the September 7, 2001 issue of Cell, Luo et al. describe the structure of LexA protein in two states, cleavable and noncleavable. This structure offers new insights into how LexA and other structurally related proteins, such as lambda and UmuD, undergo autocatalytic cleavage using a Ser-Lys dyad.
