Induction of 1,N(2)-etheno-2'-deoxyguanosine in DNA exposed to beta-carotene oxidation products.

abstract：:We previously obtained evidence for intrinsic aminopeptidase activity for leukotriene (LT)A4 hydrolase, an enzyme characterized to specifically catalyse the hydrolysis of LTA4 to LTB4, a chemotactic compound. From a sequence homology search between LTA4 hydrolase and several aminopeptidases, it became clear that they ...
