Abstract:Chemo- and regio-selective catalysis of C(sp3)-H halogenation reaction is a formidable goal in chemical synthesis. 2-oxo-glutarate (2OG) dependent non-heme iron halogenases catalyze selective chlorination/bromination of C-H bonds and exhibit high sequence and structural similarities with non-heme iron hydroxylases. How the secondary coordination sphere (SCS) of these two enzyme systems differentiate and determine their reactivity is not understood. In this work, we show that tyrosine placement in the SCS of no… Show more
