Comments
DNA photolyase catalyzes the repair of pyrimidine dimers in UV-damaged DNA in a reaction requiring visible light. These enzymes can be classified into two types, type-I and type-II.
Type-I photolyase contains FADH2 and a pterin derivative (5,10-methenyltetrahydrofolate; MTHF), whereas type-II enzyme contains FADHs and 8-hydroxy-5-deazariboflavin (8-HDF).
This enzyme belongs to the type-II enzyme group, whereas the type-I enzyme is annotated in T00085 in EzCatDB.
The reaction of this enzyme probably proceeds as follows:
(A) Excitation of 8-HDF by visible light, producing *MTHF
(B) Excitation energy transfer from *8-HDF to FADH-, giving *FADH-
(C) Electron transfer from *FADH- to Thy<>Thy, producing *FADH.
(D) The C5-C5 and C6-C6 sigma bonds of the cyclobutane ring are broken, producing .Thy- Thy
(E) Electron transfer from .Thy- Thy to *FADH., producing Thy Thy and FADH-
