Biohalogenation,mber are naturally occurring—products of nature’s halogenation processes. The majority of these naturally occurring halogenated compounds are produced by haloperoxidases, a group of enzymes widely distributed in nature that are capable of halogenating a broad spectrum of organic substrates.

,Metabolism of Halogenated Compounds—Biodehalogenation,e glutathione .-transferases. These enzymes, in general, convert nonexcretable lipophilic compounds ultimately to hydrophilic metabolites that can be eliminated in urine and/or bile. For example, oxidative replacement of halogen with hydroxyl followed by glucuronide formation is a major pathway for

Biochemistry of Inorganic Chloride,brane transport of chloride has assumed an important role in many processes, including absorption, secretion, and control of osmotic pressure, cell volume, fluid pH, and electrolyte balance. Cl. is also a common counterion in proteins, especially basic ones.

Biohalogenation,plications—the emphasis in this chapter will be placed on the biochemical processes that produce the halometabolites. Thus, the mechanism of halogenation by haloperoxidases will be reviewed, and specific examples of haloperoxidases will be given, including recently identified vanadium-containing non
