Although bromine has no known essential biological function, bromine ions are found in significant quantities in seawater
than 1900 biogenic
organobromine compounds have been discovered (reviewed by Gribble, 2003). Biosynthesis of organobromine compounds is usually catalyzed by haloperoxidases, but
halogenating (brominating or chlorinating) flavin reductases have been found in some microorganisms (reviewed
by Van Pee and Unversucht, 2003). Chemically synthesized organobromine compounds are used in industry and
agriculture and are of concern as environmental pollutants. The biodegradation of some organobromine compounds has been
and many of the pathways include enzyme-catalyzed debromination steps (reviewed by Janssen et al, 2001). Methyl transferases enable some methylotrophic bacteria to grow using methylbromide
as a sole carbon and energy
source (reviewed by McDonald et al, 2002).
