Even in the presence of functional groups that could compete in carbene-transfer reactions, enzymatic carbon–silicon bond formation proceeded with excellent chemoselectivity. WebThe protein cytochrome c constitutes a set of evolutionarily homologous structures. With the exception of many microorganisms, the mammalian type of cytochrome c is universally present in species for which oxygen serves as the terminal oxidant of metabolism. This class of protein has been utilized since the beginning of aerobic life on earth.
