  • a Triple entries record two experiments followed by their total. The first values for no and for all four accessory proteins are from the previous study (Bebenek et al. 2002).

  • b Correction factor for mutants with no mutation in lacZα and for mutants with more than one detectable mutation.

  • c Mutation frequency (MF) = (mutants)(correction factor)/(total plaques). The values from the previous collection (Bebenek et al. 2002) for no and for all four accessory proteins have changed minutely (from 164 and 247, respectively) due to small corrections.
