Identification
Name:Benzo[a]pyrene-4,5-oxide
DescriptionBenzo[a]pyrene-4,5-oxide is a member of the chemical class known as Chrysenes. These are compounds containing the polyaromatic chrysene moiety, which consists of a benzene ring fused to a phenanthrene ring system to form Benzo[a]phenanthrene. In the absence of the ycbX- and yiiM-dependent pathways, biotin sulfoxide reductase plays also a role in the detoxification pathway. (PMID 18312271)
