  • Patent number: 6927055
    Abstract: Novel protease variants derived from the DNA sequences of naturally-occurring or recombinant non-human proteases are disclosed. The variant proteases, in general, are obtained by in vitro modification of a precursor DNA sequence encoding the naturally-occurring or recombinant protease to generate the substitution of a plurality of amino acid residues in the amino acid sequence of a precursor protease. Such variant proteases have properties which are different from those of the precursor protease, such as altered wash performance. The substituted amino acid residue correspond to positions 62, 212, 230, 232, 252 and 257 of Bacillus amyloliquefaciens subtilisin.

  • Patent number: 6919190
    Abstract: The present invention provides a method of increasing the productivity of a microorganism by improving the assimilation of carbon dioxide. Specifically, the invention provides a polypeptide having phosphoenolpyruvate carboxylase activity which does not require acetyl coenzyme A for activation and is desensitized to feedback inhibition by aspartic acid, and to genes coding for this polypeptide. A gene encoding a PEP carboxylase that is not regulated by acetyl-CoA or aspartic acid can improve carbon flow from the three carbon intermediate PEP to the four carbon intermediate OAA, contribute to compounds derived from OAA, and increase amino acid biosynthesis. The invention further provides recombinant DNA molecules containing these genes, bacteria transformed with these genes, and a method of producing amino acids using the transformed bacteria.

  • Patent number: 6919440
    Abstract: A one-pot glycosylation reaction is disclosed in which a mannosyl (Man) group is enzymatically transferred to an acceptor molecule. The starting glycoside is a mannosyl 1-phosphate that is enzymatically converted to its GDP derivative via UTP and a pyrophorylase. The formed GDP derivative is used in the enzyme-catalyzed glycosyl transfer. That enzyme-catalyzed glycosyl transfer to an acceptor releases GDP that is enzymatically converted to GTP for further conversion of mannosyl 1-phosphate into its GDP derivative. Also disclosed are a recombinant ?1,2-mannosyltransferase that is enzymatically active, is dispersible in an aqueous reaction medium, and free of the transmembrane portion of the native enzyme, as well as DNA encoding that transferase, an expression vector containing exogenous DNA that encodes that enzyme and E. coli cells containing that vector.

  • Patent number: 6908991
    Abstract: The present invention relates to mutations of a subtilisin gene which result in changes in the chemical characteristics of subtilisin enzymes.
