• Intracellular Transfer Hydrogenation Mediated by Unprotected Organoiridium Catalysts

  日期：2017.7.5

  In the present work, we show for the first time that the conversion of aldehydes to alcohols can be achieved using "unprotected" iridium transfer hydrogenation catalysts inside living cells. The reactions were observed in real time by confocal fluorescence microscopy using a Bodipy fluorogenic substrate. We propose that the reduced cofactor nicotinamide adenine dinucleotide (NADH) is a possible hydride source inside the cell based on studies using pyruvate as a cellular redox modulator. We expect that this biocompatible reductive chemistry will be broadly useful to practitioners working at the interface of chemistry and the life sciences.
• ENZYMES THAT CLEAVE NON-GLYCOSIDIC ETHER BONDS BETWEEN LIGNINS OR DERIVATIVES THEREOF AND SACCHARIDES

  The patent application relates to isolated polypeptides that specifically cleave non-glycosidic ether bonds between lignins or derivatives thereof and saccharides, and to cDNAs encoding the polypeptides. The patent application also relates to nucleic acid constructs, expression vectors and host cells comprising the cDNAs, as well as methods of producing and using the isolated polypeptides for treating pulp and biomass to increase soluble saccharide yield and enrich lignin fractions.
