Direct Enzymatic Reversal of DNA Damage
This is a category of DNA repair in which the chemical modification is removed directly from the DNA. Enzymes are capable of doing this without excising bases or nucleotides.
Other sections of this encyclopedia deal with major types of DNA repair, including base excision, nucleotide excision, and mismatch repair. However, another type of repair is also important and will be presented here. At least three important types of direct reversal of DNA damage are known.
