proteinase
Breaks down proteins
Proteinase is an enzyme that breaks down proteins by cleaving the peptide bonds that link amino acids together.
The term is largely interchangeable with protease, though proteinase sometimes implies enzymes that cut within a protein chain rather than at its ends.
Digestive proteinases break food proteins into absorbable fragments.
