Error-prone SOS repair can be error-free.
Most of the mutagenesis that accompanies the SOS repair of ultraviolet light-induced lesions in the single-stranded DNA of phage S13 is eliminated when the groES or the groEL gene of Escherichia coli is defective. Therefore, this SOS mutagenesis is not a necessary consequence of what is commonly called error-prone repair, but is additionally imposed on the repair system by the GroE heat shock proteins, which are responsible for the assembly of polypeptides into multimeric structures.
