👉 A deamidase is a protein that catalyzes the enzymatic cleavage of amide bonds in amino acids. These are covalent bonds between two amino acids, and they form when the two amino acids come together to form a peptide bond. Deaminases can break these bonds into smaller peptides, which are then further broken down by other enzymes or proteins for further processing or purification. In simple terms: a deamidase is a protein that breaks down amide bonds in
