deoxyribodipyrimidine photo-lyase (medicine)


deoxyribodipyrimidine photo-lyase
<enzyme> An enzyme in yeast that is activated by light, whereupon it can reverse a previous photochemical reaction by cleaving the cyclobutane ring of the thymine dimer.

It catalyses the reactivation by light of UV-irradiated DNA and cleaves two carbon-carbon bonds in pyrimidine dimers in DNA.

Synonym: dipyrimidine photolyase, photoreactivating enzyme.

Chemical name: Deoxyribocyclobutadipyrimidine pyrimidine-lyaseRegistry number: EC 4.1.99.3
