Namevery short patch repair
TypeSYSTEM
DescriptionVery short patch (VSP) repair is a repair system that recognizes mismatches caused by deamination of 5-methylcytosine (5meC). Cytosine is modified to 5meC by the product of the dcm gene. Vsr is an endonuclease that creates a nick to allow the repair. In Escherichia coli, the second C of the DNA motif CCWGG (where W is A or T) is methylated; deamination yields T:G mispairs reccognized by the vsr gene product. The vsr gene typically is found very close to the dcm gene, and is essentially restricted to a subset of those genomes that carry dcm.
