  • n. An endopeptidase enzyme that cleaves peptides at the carboxyl side of tyrosine, tryptophan, and phenylalanine amino acids.

Etymologies

chym(e) + trypsin.

Examples

  • Next, the smaller proteins move into the small intestine, where pancreatic enzymes, trypsin and chymotrypsin, continue the breakdown of proteins into amino acids.

    Carrie Wiatt, M.S.: Fruit: Fads, Digestion and Cleanses

  • Northrop, however, managed to crystalize three digestive enzymes, pepsin, trypsin and chymotrypsin, and by painstaking experiments shown them to be pure proteins.

  • Proteinase inhibitors, affecting trypsin and chymotrypsin, have been found in seeds of A. cowleana and other species. but only at levels similar to those found in peas or beans-much lower than levels in soybeans or winged beans (Kortt, 1984).

    Chapter 48

  • The chymotrypsin crystals were twinned and therefore difficult to work with, and so Perutz continued with haemoglobin.

    Max F. Perutz - Biography

  • Bernal, Fankuchen, and Perutz [Nature, 141 (1938) 523] published a joint paper on X-ray diffraction from crystals of haemoglobin and chymotrypsin.

    Max F. Perutz - Biography

  • Princeton began to work on the purification of the protein-splitting enzymes met with in the digestive apparatus and gradually succeeded in obtaining a number of them in crystallized form, e.g. the pepsin met with in the gastric juice and the trypsin and chymotrypsin in the pancreas.

    Nobel Prize in Chemistry 1946 - Presentation Speech

  • In 1929 he isolated pepsin in pure crystalline form by techniques which were later used by himself and other workers to crystallize trypsin, chymotrypsin, carboxypeptidase, and pepsinogen.

    John H. Northrop - Biography

  • The most frequently used biological molecules included in the digestion models were digestive enzymes (pancreatin, pepsin, trypsin, chymotrypsin, peptidase, ╬▒-amylase, and lipase), bile salts, and mucin.

  • First, we investigated the consequences of moisture sorption on the stability and structural conformation of the model enzyme alpha-chymotrypsin (alpha-CT) under controlled humidity conditions.

  • Samples were subjected to reduction with dithiothreitol, alkylation with iodoacetamide, and in-gel digestion with trypsin or chymotrypsin overnight at pH 8.3, followed by reversed-phase microcapillary/tandem mass spectrometry (LC/MS/MS).
