File Description | Methyl-directed mismatch repair If any mismatch escapes the proof reading mechanisms it will cause distortion of the helix. This can be detected and repaired but it is important that the repair enzyme can distinguish the new strand from the old. Mismatch repair MMR system is an excision/resynthesis system that can be divided into 4 phases: (i) recognition of a mismatch by MutS proteins, (ii) recruitment of repair enzymes (iii) excision of the incorrect sequence, (iv) resynthesis by DNA polymerase using the parental strand as a template. |
