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.

The invention provides an enzyme with cytochrome P450 activity with mutations at the 109 and/or 198 positions based on P450.sub.SeuC10 from Streptomyces eurythermus NRRL 2539. The invention extends to related nucleic acid material and microorganisms, kits containing the enzyme, methods of producing the enzyme and methods of using the enzyme to generate oxidised organic compounds.

An object of the present invention is to provide DNA of a glycoalkaloid biosynthetic enzyme of a solanaceous plant (Solanaceae) such as a potato. The present invention relates to a protein having glycoalkaloid biosynthetic enzyme activity of a solanaceous plant such as a potato and a method for producing/detecting a novel organism using a gene encoding the protein.

The present invention is drawn to artificial metalloenzymes for use in cyclopropanation reactions, amination and CH insertion.

Disclosed herein are enzymes useful for the dealkylation of aromatic substrates, including the conversion of guaiacol or guaethol to catechol. Methods of converting aromatic substrates found in lignin-based feedstocks such as pyrolysis oil into products such as catechol are also disclosed. Also presented herein are methods for rapidly evolving and optimizing genetic regions.

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.

The present disclosure relates, at least in part, to the production of delta-lactones from fatty acid substrates via a batch fermentation method in an engineered microbe using a recombinant cytochrome P450 monooxygenase.

The present invention provides improved P450-BM3 variants with improved activity. In some embodiments, the P450-BM3 variants exhibit improved activity on a 1-tert-Butoxycarbonylaminocyclopentanoic acid substrate.

The present disclosure relates to the biosynthesis of indigoid dye precursors and their conversion to indigoid dyes. Specifically, the present disclosure relates to methods of using polypeptides to produce indigoid dye precursors from indole feed compounds, and the use of the indigoid dye precursors to produce indigoid dyes.

The present disclosure provides a recombinant adeno-associated vector comprising a codon-optimized sequence encoding CYP4V2 linked to selected gene expression regulatory sequences and its use in treating Bietti Crystalline Dystrophy (BCD).
