Enterokinaseenterokinase[‚ent·ə·rō′kī‚nās]Enterokinasea proteolytic enzyme of the class of endopeptidases. Enterokinase is a complex protein containing carbohydrates (glycoprotein). It has been discovered in man and some other mammals. The enzyme is secreted by cells of the mucosa of the duodenum into the lumen of the intestine, where it activates trypsinogen, which enters through the pancreatic duct. The enzyme trypsin thus formed activates trypsinogen and all the other proteolytic enzymes of pancreatic secretion. The direct participation of enterokinase in the digestion of food is insignificant, since only an extremely small quantity is present. enterokinaseenteropeptidase[en″ter-o-pep´tĭ-dās]en·ter·o·pep·ti·dase(en'tĕr-ō-pep'ti-dās),enterokinase(ĕn′tə-rō-kī′nās′, -nāz′, -kĭn′ās′, -āz′)TMPRSS15A gene on chromosome 21q21 that encodes a serine protease responsible for activating pancreatic proteolytic proenzymes by catalysing the conversion of trypsinogen to trypsin, which in turn activates other proenzymes, including chymotrypsinogen, procarboxypeptidases and proelastases. It is localised at the intestinal brush border.Molecular pathology Defects in TMPRSS15 are a cause of enterokinase deficiency. enterokinaseSee ENTEROPEPTIDASE.enterokinasesee ENTEROPEPTIDASE.enterokinase) an ENZYME secreted by cells of the DUODENUM, which catalyses the conversion of inactive TRYPSINOGEN in the PANCREATIC JUICE to active TRYPSIN.See ENTK enterokinase
