FIG. 4.
Yields of BMH-induced cross-linking in FliG proteins with one or two Cys replacements. (A) Summary of yields for Cys at positions in the middle domain (FliGM). The shaded bars indicate the yields of cross-linked dimer, and the solid bars indicate the combined yields of all multimers larger than dimers. The error bars indicate the standard deviations of two or more determinations. (B) Summary of yields of cross-linked dimers for Cys at positions in the C-terminal domain. Larger multimers were not observed for any of the Cys replacements in FliGC.
