An enzyme that degrades proteins is called neutral protease, sometimes known as neutral protease enzyme. It is known as “neutral” because it performs best when the pH is neutral, which is usually around pH 7. Numerous species, including bacteria, fungus, and plants, produce neutral proteases.

Proteins are broken down into smaller peptides and amino acids by neutral protease, which operates on the peptide bonds in proteins. Numerous biological systems and commercial operations depend on this enzymatic activity.

Neutral proteases have a role in protein digestion in the human body. They are created by the pancreas and secreted into the small intestine where they combine with other digestive enzymes to break down ingested proteins into amino acids. The body then absorbs and uses these amino acids.
