摘要:This invention provides libraries of recombinant derivatizing enzymes that are useful for biocatalytic synthesis of derivatives oforganic molecules, including lead compounds for pharmaceutical use. The recombinant derivatizing enzymes catalyze reactions such as modification or replacement of functional groups on the organicmolecules, or addition of chemical moieties onto preexisting functional groups. The use of recombinant enzyme libraries enables one to obtain enzymes that catalyze the formation of organic molecule derivatives that could not otherwise be made using only naturally occurring enzymes.

摘要:The present invention relates to methods of preparing carbon monoxide (CO) and hydrogen (H 2 ) by reacting biomass, a biomass component (e.g., lignin, ligno-cellulose, cellulose, hemiceullose or combination thereof) or a carbohydrate from any source with a polyoxometalate catalyst such as H 5 PV 2 Mo 10 O 40 , or solvates thereof, in the presence of a concentrated acid, under conditions sufficient to yield carbon monoxide (CO); followed by electrochemical release of hydrogen (H 2 ). The carbon monoxide (CO) and hydrogen (H 2 ) may be combined in any desired proportion to yield synthesis gas (Syngas). The present invention further relates to methods for preparing H 2 , CO and formic acid/formaldehyde from biomass, a biomass component and/or from carbohydrates.
