Purification and partial characterization of (6-4) photoproduct DNA photolyase from Xenopus laevis

Photochem Photobiol. 1996 Mar;63(3):292-5. doi: 10.1111/j.1751-1097.1996.tb03028.x.

Abstract

The (6-4) photoproduct DNA photolyase was detected in two vertebrate animals Crotalus atrox (rattlesnake) and Xenopus laevis (South African clawed toad). The enzyme was extensively purified from X. laevis and characterized. The highly purified enzyme is fluorescent with an excitation maximum at 420-440 nm and emission maximum at 460-480 nm. The photorepair action spectrum matches the fluorescence excitation spectrum with a 430 nm maximum.
