ComM facilitates the resolution of chromosome dimers generated during transformation. Reduction in merodiploid frequency in comM − strains compared with that in wild-type and cbpD C75A cells. Comparison of transformation efficiency using as donor a mixture of PCR fragments that promote merodiploid formation and enables their selection52. Values and standard deviations are based on data from three independent experiments. Recipient strains used: wild-type (WT, R1501), cbpD − (R3966), cbpD − comM − (R3967), cbpD − recO − xerS − (R3970), cbpD − comM − recO − xerS − (R3973)
