Secondary Accession Numbers Not Available
Name Plasma kallikrein
Description Not Available
Synonyms
  1. Fletcher factor
  2. Kininogenin
  3. Plasma kallikrein heavy chain
  4. Plasma kallikrein light chain
  5. Plasma prekallikrein
Gene Name KLKB1
Protein Type Enzyme
Biological Properties
General Function Involved in serine-type endopeptidase activity
Specific Function The enzyme cleaves Lys-Arg and Arg-Ser bonds. It activates, in a reciprocal reaction, factor XII after its binding to a negatively charged surface. It also releases bradykinin from HMW kininogen and may also play a role in the renin-angiotensin system by converting prorenin into renin
