Spore photoproduct lyase (SP lyase) is a member of the radical SAM superfamily and catalyzes the direct reversal of the spore photoproduct (SP, 5-thyminyl-5,6dihydrothymine), a thymine dimer specific to bacterial spores, to two thymines. SP lyase requires S-adenosyl-L-methionine (SAM) and a redox active [4Fe-4S] cluster for catalysis. Mössbauer analysis of anaerobically purified SP lyase defined the presence of a mixture of cluster states with the majority (40%) as [2Fe-2S] clusters and a… CONTINUE READING
