RECOMBINANT STRAIN CONTAINING TRUNCATED TUP1, AND COMPOSITION FOR ALCOHOL-PRODUCING CONTAINING THE SAME

摘要

PURPOSE: A recombinant strain containing truncated Tup1 polypeptide and a composition containing the same for producing alcohol are provided to improve alcohol resistance and to ensure alcohol productivity. CONSTITUTION: A recombinant strain contains first polypeptides having the function of an expression inhibition domain is truncated from Tup1 and a second polypeptide in which Ino1 is expressed. The first polypeptide contains amino acid sequence in which one or more among 288-389th amino acids are substituted, inserted, added or truncated. The second polypeptide has an amino acid sequence having 70% or more sequence homology with an amino acid of sequence number 2. The carboxyl terminal end domain is a truncated Tup1 polypeptide. A composition for producing alcohol contains the recombinant strand.
