kallikrein


kallikrein
A group of enzymes ( e.g., plasma, tissue, pancreatic, urinary, submandibular k.) that can convert kininogen by proteolysis to bradykinin or kallidin; trypsin and plasmin can also effect the conversion; plasma k. activates the Hageman factor and acts on kininogen. Tissue k. is a serine endopeptidase that can generate kallidin from kininogen. SYN: kininogenase, kininogenin.
- human glandular k. 3 (hK3) SYN: prostate-specific antigen.
