Interactions between UbiK and the other Ubi proteins. A bacterial two-hybrid system was used to detect in vivo protein-protein interactions. Values of β-galactosidase activities, calculated in Miller units, with standard errors are shown: pT25-ubiK (A) or pT18-ubiK (B) were analyzed with ubiJ, -E, -I, -K, -B, -D, -G, -A, -X, -H, or -F genes, respectively.
