The present invention provides compositions and methods for catalyzing the formation of carbon-silicon bonds using heme proteins. In certain aspects, the present invention provides heme proteins, including variants and fragments thereof, that are capable of carrying out in vitro and in vivo carbene insertion reactions for the formation of carbon-silicon bonds. In other aspects, the present invention provides methods for producing an organosilicon product, the method comprising providing a silicon-containing reagent, a carbene precursor, and a heme protein; and combining the components under conditions sufficient to produce an organosilicon product. Host cells expressing the heme proteins are also provided by the present invention.
