Abstract:
PSEUDOMONAS LIPASE Nucleic acid sequences, particularly DNA sequences, coding for all or part of a lipase of Pseudomonas sp. ATCC 21808, wherein said lipase has the amino acid sequence encoded by the nucleotide sequence of the SacI/HindIII insert of plasmid pSG312 deposited with the American Type Culture Collection, expression vectors containing the DNA sequences, host cells containing the expression vectors, and methods utilizing these materials. The invention also concerns polypeptide molecules comprising all or part of a lipase of Pseudomonas sp. ATCC 21808, wherein said lipase has the amino acid sequence encoded by the nucleotide sequence of the SacI/HindIII insert of plasmid pSG312 deposited with the American Type Culture Collection, and methods for producing these polypeptides molecules.
Abstract:
The instant invention provides a novel amino acid dehydrogenase can be utilized to convert keto acids to amino acids more efficiently and in a more cost effective manner. The instant invention also provides knock-out cells which lack glutamate dehydrogenase.
Abstract:
A lubricant sheet (10) for use in drilling holes in a printed circuit board, including a lubricant layer. The lubricant layer includes at least a water-soluble lubricant. In an alternative embodiment, the lubricant layer also includes an inversely-soluble lubricant. The water-soluble lubricant is preferably polyethylene glycol (14), having a weight average molecular weight between about 4,500 and 7,000. The inversely-soluble lubricant is preferably polyalkylene glycol (14). The lubricant sheet (10) may also include a porous, fibrous, organic sheet impreganted with lubricant and/or a polymer-impregnated paper.
Abstract:
This invention relates to a recombinant Pichia pastoris formate dehydrogenase (FDH) enzyme that catalyzes the oxidation of formate to carbon dioxide and the simultaneous reduction of nicotinamide adenine dinucleotide (NAD+) to its reduced form (NADH). Also related are isolated nucleic acids encoding P. pastoris FDH polypeptides, and fragments and variants thereof, as well as vectors and host cells comprising these nucleic acids. Further related are isolated, recombinant P. pastoris FDH polypeptides, and fragments and variants thereof, and antibodies that specifically bind to P. pastoris FDH polypeptides, fragments, or variants. The invention also relates to methods of obtaining isolated P. pastoris FDH nucleic acids, polypeptides, and antibodies, and methods of using P. pastoris FDH in various reactions for industrial or pharmaceutical applications.
Abstract:
The invention relates to a process for the enzymatic, stereoselective reduction of ketone compounds to provide chiral alcohols, for example the compound of formula (Ib).
