An<unk>  is a drug that inhibits one or more<unk>  enzymes.<unk> s are one of two types of proteases (enzymes that break down proteins and peptides), the other being exopeptidases.<unk> s cleave peptide bonds of non-terminal amino acids (that is, they cut proteins/peptides into two chains), whereas exopeptidases break terminal bonds, resulting in the release of a single amino acid or dipeptide from the peptide chain.
