Glutaminase, glutaminase gene, novel recombinant DNA, and process for manufacturing glutaminase

摘要

Glutaminase which comprises (a) a protein comprising an amino acid sequence shown in SEQ ID NO: 2, or (b) a protein which comprises an amino acid sequence having deletion, substitution, or addition of one or plurality of amino acids relative to the amino acid sequence (a), and has glutaminase activity. A glutaminase gene which encodes (a) a protein comprising an amino acid sequence shown in SEQ ID NO: 2, or (b) a protein which comprises an amino acid sequence having deletion, substitution, or addition of one or a plurality of amino acids relative to the amino acid sequence (a), and has glutaminase activity. The present invention enables glutaminase to be produced efficiently and thus greatly contributes to the relevant industries.
