IntEnz Enzyme Nomenclature


Accepted name:
spore photoproduct lyase
Other names:
SP lyase
Systematic name:
spore photoproduct pyrimidine-lyase




This enzyme is a member of the 'AdoMet radical' (radical SAM) family. The enzyme binds a [4Fe-4S] cluster. The cluster is coordinated by 3 cysteines and an exchangeable SAM molecule [3]. The 5'-deoxy-adenosine radical formed after electron transfer from the [4Fe-4S] cluster to the S-adenosyl-L-methionine, initiates the repair by abstracting the C-6 hydrogen of the spore photoproduct lesion. During the second part of the repair process the SAM molecule is regenerated [3].
