Disclosed is an isolated nucleic acid that, under stringent conditions, hybridizes to a probe containing one of SEQ ID NOs:1-11; or its complementary sequence. Also disclosed are (1) a transformed cell or a transgenic plant containing such a nucleic acid and (2) a transformed cell or a transgenic plant having a reduced level(s) of one or more of the Tubby-like proteins. Also within the scope of the invention are methods for making the transformed cells or transgenic plants.

    摘要: The present invention provides mutant-type lipases which demonstrate superior lipolytic and esterific activities. The mutant-type lipases are characterized by an amino acid alteration at the residue immediately followed either the serine residue or the histidine residue or both residues of the Ser-His-Asp catalytic triad. The Ser-His-Asp catalytic triad is known to be the three residues, although occur far apart in the amino acid sequence of a lipase, that contribute to the hydrolytic activity in the active site of the lipase. The amino acid residue that follows the serine residue of the Ser-His-Asp catalytic triad is alanine. The amino acid residue that follows the histidine residue of the Ser-His-Asp catalytic triad is isoleucine. The wild-type lipase is preferably originated from Staphylococcus, particularly Staphylococcus epidermindis. The present invention also relates to a method for preparing the mutant-type lipases by site-directed mutagenesis using PCR and a method for utilizing the mutant-type lipase to catalyze synthesis of flavor esters to be used in food industry.

    摘要: The present invention features an isolated nucleic acid that includes a mutant DNA encoding a Candida rugosa lipase, wherein the mutant DNA is 80% identical to a wild-type DNA encoding the Candida rugosa lipase, and includes at least 12 (e.g., 13, 15, 17, or all) universal serine codons corresponding to CTG codons in the wild-type DNA. Each of the universal serine codons, independently, is TCT, TCC, TCA, TCG, AGT, or AGC. The Candida rugosa lipase can be Candida rugosa lipase 1, 2, 3, 4, 5, or 8.

    摘要: The present invention relates to the isolation and functional identification of a novel acid and heat resistant trehalose synthase enzyme cloned from Picrophilus torridus. More particularly, the present invention discloses the DNA sequence for the Picrophilus torridus trehalose synthase gene, PTTS, which when expressed in a heterologous host such as Escherichia coli, provides enzymatic activity that catalyzes the direct interconversion of maltose and trehalose through intramolecular transglycosylation. Additionally, the present invention teaches methods of use of PTTS for production of trehalose as well as for production of various useful compounds comprising trehalose.
