enteropeptidase

 [en″ter-o-pep´tĭ-dās]
an enzyme of the intestinal juice secreted by the duodenal mucosa; it activates the proteolytic enzyme of the pancreatic juice by converting trypsinogen into trypsin.

en·ter·o·pep·ti·dase

(en'tĕr-ō-pep'ti-dās),
An intestinal proteolytic glycoenzyme from the duodenal mucosa that converts trypsinogen into trypsin (removes a hexapeptide from trypsinogen).
Synonym(s): enterokinase

enterokinase

(ĕn′tə-rō-kī′nās′, -nāz′, -kĭn′ās′, -āz′)
n.
An enzyme secreted by the upper intestinal mucosa that catalyzes the conversion of trypsinogen to trypsin.

enterokinase

[en′tirōkī′nās]
Etymology: Gk, enteron + kinesis, movement, ase, enzyme
an intestinal juice enzyme that activates the proteolytic enzymes in pancreatic juice as they enter the duodenum.

TMPRSS15

A 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.

enterokinase

) an ENZYME secreted by cells of the DUODENUM, which catalyses the conversion of inactive TRYPSINOGEN in the PANCREATIC JUICE to active TRYPSIN.

enterokinase

the intestinal hormone that activates trypsinogen into becoming active trypsin.

Trypsin is produced in the exocrine pancreas as two major proenzymes, trypsinogen-1 (cationic) and trypsinogen-2 (anionic), which typically are activated in the duodenum by enterokinase to trypsin-1 and trypsin-2, respectively.
