Photolyases (EC 4.1.99.3) are DNA repair enzymes that repair damage caused by exposure to ultraviolet light. These enzymes require visible light (from the violet/blue end of the spectrum) both for their own activation [1] and for the actual DNA repair. [2] The DNA repair mechanism involving photolyases is called photoreactivation.
Azo violet (Magneson I; [1] p-nitrobenzeneazoresorcinol) is an azo compound with the chemical formula C 12 H 9 N 3 O 4. It is used commercially as a violet dye and experimentally as a pH indicator, appearing yellow below pH 11, and violet above pH 13. [2] It also turns deep blue in the presence of magnesium salt in a slightly alkaline, or basic ...

RecQ helicase is a family of helicase enzymes initially found in Escherichia coli [1] that has been shown to be important in genome maintenance. [2] [3] [4] They function through catalyzing the reaction ATP + H 2 O → ADP + P and thus driving the unwinding of paired DNA and translocating in the 3' to 5' direction.
