FIELD: biotechnology.
SUBSTANCE: following is proposed: a nucleotide for the enzymatic production of L-threonine, containing a promoter nucleotide sequence formed by a mutation consisting of replacing adenine (A) with guanine (G) at the 289th base of the nucleotide sequence presented in SEQ ID NO: 13. An expression cassette containing the specified nucleotide, a vector containing the specified nucleotide, a recombinant bacterium containing the specified nucleotide, their use for the enzymatic production of L-threonine, as well as a method for constructing the specified recombinant bacterium are also proposed.
EFFECT: invention ensures the production of L-threonine in high concentration.
