LEECH-DERIVED TRYPTASE INHIBITOR/TRYPSIN COMPLEX
Overview
BACKGROUND: Tryptase is a trypsin-like serine proteinase stored in the, cytoplasmic granules of mast cells, which has been implicated in a number, of mast cell related disorders such as asthma and rheumatoid arthritis., Unlike almost all other serine proteinases, tryptase is fully active in, plasma and in the extracellular space, as there are no known natural, inhibitors of tryptase in humans. Leech-derived tryptase inhibitor (LDTI), a protein of 46 amino acids, is the first molecule found to bind tightly, to and specifically inhibit human tryptase in the nanomolar range. LDTI, also inhibits trypsin and chymotrypsin with similar affinities. The, structure of LDTI in complex with an inhibited proteinase could be used as, a template for the development of low molecular weight tryptase, ... [(full description)]
