  • Patent number: 6410716
    Abstract: SU1, a starch debranching enzyme active in maize endosperm (Zea mays), and the cDNA and genomic sequences encoding SU1 are disclosed. The amino acid sequence is significantly similar to that of bacterial isoamylases, enzymes that hydrolyze &agr;-(1→6) glycosidic bonds. Amino acid sequence similarity establishes SU1 as a member of the &agr;-amylase superfamily of starch hydrolytic enzymes. Also disclosed are antibodies reactive with the SU1 protein, methods of producing antibodies to the SU1 protein, methods of producing fusion proteins including SU1 as well as recombinant SU1 and methods of producing transgenic plants with a modified su1 gene. The native or expressed SU1 protein can serve as a replacement for the bacterial and fungal enzymes currently used in the starch processing industry.

  • Patent number: 6323001
    Abstract: Two nucleotide sequences encoding two different polypeptides found in yeast trehalose synthase have been isolated and cloned. A third polypeptide has been isolated from the enzyme and characterized, and a method is provided to isolate and clone the nucleotide sequence encoding this polypeptide. The coding sequences can be inserted into suitable vectors and used to transform host cells. The transformed cells will produce increased amounts of trehalose compared to the untransformed wild types and have increased tolerance to a variety of stresses, in particular to decreased availability of water. The invention may be used to improve the stress tolerance of organisms, to increase the storage life of foodstuffs and to produce trehalose economically on an industrial scale in an organism (e.g. baker's yeast) that is a traditional and safe foodstuff.

  • Patent number: 6252140
    Abstract: The invention is directed to novel promoters or mutants thereof from Chlorella virus DNA methyltransferase genes. A Chlorella virus gene promoter is operably linked to a first and/or second DNA sequence encoding a gene that is different from the Chlorella virus gene to form an expression cassette. An expression cassette can be introduced into prokaryotic and/or eukaryotic cells and can provide for a high level of expression of the gene encoded by the first and/or second DNA sequence. The invention also provides a method for screening other Chlorella virus genes for promoters that can function to express a heterologous gene in prokaryotic and/or eukaryotic hosts.

  • Patent number: 6235971
    Abstract: Introducing sucrose phosphorylase activity into plants by transformation with a gene for the enzyme increases the rate of sucrose hydrolysis, leading to increased starch, oil, and/protein levels. Sucrose phosphorylase genes from Streptococcus mutans and Leuconostoc mesenteroides have been found particularly advantageous for use in the present invention. Surprisingly, in potatoes transformed to express these genes in tubers, reduced bruise discoloration susceptibility and increased uniformity of starch deposition throughout the tuber are achieved.
