Title:
MODIFIED PROTEIN GLUTAMINASE
Document Type and Number:
WIPO Patent Application WO/2023/171778
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a protein glutaminase in which a decrease in reactivity due to a high temperature is suppressed. This protein glutaminase is formed of a polypeptide having an amino acid sequence obtained by introducing a substitution of a predetermined amino acid residue or amino acid sequence to an amino acid residue or an amino acid sequence at a specific location in the amino acid sequence indicated in SEQ ID NO: 1. In the protein glutaminase, a decrease in reactivity at a high temperature is suppressed more as compared to the polypeptide having the amino acid sequence indicated by SEQ ID NO: 1.
