Abstract: Non-naturally occurring amine dehydrogenases (AmDH) and methods of use thereof the produce chiral amines are disclosed. The AmDH are variants of amino acid dehydrogenases. AmDH based on phenylalanine, leucine, and valine scaffolds are provided. The AmDH typically have one, two, three, four, or more amino acid alterations relative to the scaffold. The alterations to the scaffold result in an enzyme that accepts the analogous ketone, such as methyl isobutyl ketone (MIBK), instead of the wild-type ?-keto acid. Chimeric AmDH are also disclosed. The chimeras are fusion proteins that include a substrate binding domain from a first AmDH and a cofactor binding domain from a second AmDH. In a preferred embodiment, one of the domains is from a PheDH-based AmDH and one of the domains is from a LeuDH-based AmDH.

Abstract: The present application provides methods of producing antimicrobial peptides (AMPs) in a cell, for example by expression a fusion protein that includes small ubiquitin related modifier (SUMO) and an AMP in the cell. Also provided are nucleic acid and protein sequences of SUMO-AMP fusion proteins, and kits that include such molecules.

Abstract: The present invention is directed to a new NADH oxidase from Lactobacillus, nucleic acids encoding the NADH oxidase, methods of producing the NADH oxidase, as well as there use in producing improved NADH oxidase enzymes and for producing chrial enantiomer-enriched organic compounds, such as alcohols and/or amino acids.

Abstract: Compositions and methods of using a carbonyl reductase from Lactococcus lactis (LLCR or LL-CR) are provided. One aspect provides an isolated polypeptide from Lactococcus lactis, wherein the polypeptide is an (R)-specific carbonyl reductase or a fragment thereof and reduces acetophenone or alph,beta-unsaturated carbonyl compound to form a reduced R enantiomeric product. In certain aspects, LLCR is stable in from about 1.0% to about 60% organic solvent or more than 10%, 20%, 30%, 40% or 50% organic solvent.

Abstract: This invention involves a process for selecting and producing eukaryotic alkaline phosphatase in yeast. Yeast cells are subjected to multiple transformations using a vector comprising a first resistance marker gene and the alkaline phosphatase gene. Those strains that grow in media containing the first resistance marker are further transformed using a vector comprising a second selection marker gene and the alkaline phosphatase gene. Transformants that grow in media containing the second selection marker are selected for expressing the eukaryotic alkaline phosphatase.

Abstract: The invention concerns a process for the recombinant production and expression of eukaryotic alkaline phosphatase in yeast cells in which in particular a DNA coding for a eukaryotic highly active alkaline phosphatase having a specific activity above 3000 U/mg is used. The invention additionally concerns a process for inserting corresponding nucleic acid sequences into a vector for expression in methylotrophic yeast strains and it concerns appropriate vectors and host strains.
