Protein splicing of a recombinase intein induced by ssDNA and DNA damage.

Abstract excerpt

Inteins (or protein introns) autocatalytically excise themselves through protein splicing. We challenge the long-considered notion that inteins are merely molecular parasites and posit that some inteins evolved to regulate host protein function. Here we show substrate-induced and DNA damage-induced splicing, in which an archaeal recombinase RadA intein splices dramatically faster and more accurately when provided...
