This invention relates to modified hydroxylases. The invention further relates to cells expressing such modified hydroxylases and methods of producing hydroxylated alkanes by contacting a suitable substrate with such cells.

Alkane oxidation by modified hydroxylases

This disclosure provides a method of preparing a silanol-functional organosilicon compound with a cytochrome P450 variant that facilitates the oxidization of a silyl hydride group to a silanol group in the presence of oxygen. The method includes combining the cytochrome P450 variant and an organosilicon compound having at least one silicon-bonded hydrogen atom to give a reaction mixture and exposing the reaction mixture to oxygen to oxidize the organosilicon compound, thereby preparing the silanol-functional organosilicon compound. Cytochrome P450 variants suitable for use in the method are also disclosed, along with methods for engineering and optimizing the same. Nucleic acids encoding the cytochrome P450 variants and compositions, expression vectors, and host cells including the same are also disclosed.

Method of preparing silanols with selective cytochrome P450 variants and related compounds and compositions

Disclosed herein are engineered light-sensitive proteins, for example channelrhodopsins and variants thereof. Also disclosed are compositions for expressing the light-sensitive proteins in cells, tissues, organs and subjects, and methods for using the light-sensitive proteins to, for example, enable minimally-invasive neuronal circuit interrogation in living organism, and treat neuronal and ocular disorders.
