    摘要: The present invention relates to a reverse transcriptase having improved thermostability, more precisely a mutant reverse transcriptase with improved thermostability by substitution of one or more amino acids selected from the group consisting of the 63rd glutamine (Q63), the 264th lysine (K264), the 295th lysine (K295), the 306th threonine (T306), the 346th glutamic acid (E346), the 408th proline (P408), the 438th histidine (H438), and the 454th asparagin (N454) of the amino acid sequence of M-MLV originated reverse transcriptase represented by SEQ. ID. NO: 1 with other amino acids. The mutant reverse transcriptase of the present invention demonstrates excellent thermostability, compared with the wild type reverse transcriptase. Therefore, it is advantageous to obtain the target cDNA with stable reverse transcription activity even in the presence of RNA that can form the stable secondary structure at a high temperature.

    摘要: The present invention relates to a lactic acid bacterium isolated from human mother's milk, more precisely a Lactobacillus gasseri BNR17 strain that is isolated from Korean mother's milk and has excellent probiotic activity including acid resistance, bile acid resistance and antimicrobial activity and weight gaining inhibitory effect as well. Again, the Lactobacillus gasseri BNR17 of the present invention has excellent acid resistance, bile acid resistance, enteric absorption activity and antimicrobial activity against pathogenic microorganisms, in addition to the weight gaining inhibitory effect by synthesizing indigestible polysaccharides from monosaccharides included in food taken and releasing the synthesized polysaccharides out of the body. Therefore, the strain of the invention, owing to such beneficiary effects, can be effectively used not only for the production of fermented milk, other fermented food products and animal feeds but also for the production of live cell products and food additives for preventing weight gaining.
