The flavoprotein L-hydroxynicotine oxidase (LHNO) catalyzes an early step in the bacterial catabolism of nicotine. Although the structure of the enzyme establishes that it is a member of the monoamine oxidase family, LHNO is generally accepted to oxidize a carbon-carbon bond in the pyrrolidine ring of the substrate and has been proposed to catalyze the(More)
The anthrax protective antigen (PA) is an 83 kDa protein that is one of three protein components of the anthrax toxin, an AB toxin secreted by Bacillus anthracis. PA is capable of undergoing several structural changes, including oligomerization to either a heptameric or octameric structure called the prepore, and at acidic pH a major conformational change(More)
The flavoenzyme l-6-hydroxynicotine oxidase is a member of the monoamine oxidase family that catalyzes the oxidation of (S)-6-hydroxynicotine to 6-hydroxypseudooxynicotine during microbial catabolism of nicotine. While the enzyme has long been understood to catalyze oxidation of the carbon-carbon bond, it has recently been shown to catalyze oxidation of a(More)
