Lessons from the rifamycin biosynthetic gene cluster.

abstract：:In the past five to ten years, it has become increasingly apparent that the function of Fe-S clusters is not limited to electron transfer, a function implicit in their discovery. We now know that the vulnerability of these structures to oxidative destruction is used by nature in sensing O2, iron, and possibly also nit...

abstract：:The nature of the oxidized halogen intermediate in vanadium bromoperoxidase has recently been shown to depend on the nature of the organic substrate. For example, in the presence of indoles, vanadium bromoperoxidase does not release a freely diffusible oxidized halogen intermediate (such as HOBr+/-BR2+/-Br3-). Regiose...
