Ethylenediamine-N, N'-disuccinic acid: a protein having ethylenediamine lyase activity and a gene encoding the same

摘要

The present invention relates to an ethylenediamine-N, N'-disuccinic acid: DNA comprising a nucleotide sequence encoding a polypeptide having ethylenediamine lyase activity, wherein the polypeptide is at least an amino acid sequence represented by SEQ ID NO: 1 or in this amino acid sequence. DNA having an amino acid sequence in which one amino acid has been deleted, substituted, or added, a recombinant plasmid containing the DNA, a host transformed with the recombinant plasmid, or a diaminoalkylene-N, N 'using the transforming host It relates to a process for preparing disuccinic acid. In addition, the present invention has an amino acid sequence represented by SEQ ID NO: 1 or an amino acid sequence in which at least one amino acid is deleted, substituted or added in this amino acid sequence, and has an ethylenediamine-N, N'-disuccinic acid: ethylenediamine lyase activity. It relates to a polypeptide having.
