Noun1.proteinase - any enzyme that catalyzes the splitting of proteins into smaller peptide fractions and amino acids by a process known as proteolysis
caspase - any of a group of proteases that mediate apoptosis
enzyme - any of several complex proteins that are produced by cells and act as catalysts in specific biochemical reactions
angiotensin converting enzyme, angiotensin-converting enzyme, ACE - proteolytic enzyme that converts angiotensin I into angiotensin II
plasminogen activator, urokinase - protease produced in the kidney that converts plasminogen to plasmin and so initiates fibrinolysis
renin - a proteolytic enzyme secreted by the kidneys; catalyzes the formation of angiotensin and thus affects blood pressure

Proteinase secretion was estimated as Pz values, calculated by measuring the diameters of degradation zones and then by dividing the diameter of the colony by the diameter of the colony together with zone of clearance (23,26).
The effect of proteinase inhibitors in food protein hydrolysis by digestive proteinases of white shrimp (Penaeus vannamei) larvae.
Currently, the term "peptidase" is also used equivalently with "protease" and "proteinase." Peptidase was restricted to the enzymes included in subsubclasses EC 3.4.11-19, the exopeptidases in the Enzyme Nomenclature (1984), while the term "proteinases" was previously used for the enzymes included in subsubclasses EC 3.4.21-99 having the same meaning as "endopeptidase." However, the terms "protease" and "proteinase" are still preferred by many scientists [3].
Although ANCA-GN from a clinical point of view usually is regarded as one disease, it is associated with 2 different autoantibodies, proteinase 3 (PR3) and myeloperoxidase (MPO).
MPO-ANCA was positive (110U/mL, 3.4 is a reference value in our hospital), and proteinase 3- (PR3-) ANCA was slightly positive (3.9 U/mL, 3.4 is a reference value in our hospital).
The mature [PrP.sup.Sc] aggregates are characterized by their resistance to proteinase K digestion, apple-green birefringence when stained with Congo red, and their ability to enhance the fluorescence emission of the dye thioflavin T.
This has been demonstrated by transferring proteinase inhibitor oryzacystatin II (OCII) from rice to tobacco, which enhances tobacco resistance to the Colorado potato beetle, Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae) (Cingel et al.
The least effective method was to digest this pellet with proteinase K followed by phenol-chloroform extraction, alcohol precipitation, and resuspension; the authors report a limit of detection (LOD) of 117 tachyzoites.
We used the Pacific whiteleg shrimp as the model to investigate the transcript changes that lead to proteinase activity in the digestive system during ontogeny.
(8,9,22,23,24) Interestingly, the study by Euzebio-Alves et al., (14) clearly demonstrated that epithelial cells and leukocytes present in the GCF express PAR-2, and that the presence of the potential activators, gingipains and neutrophil serine proteinase 3, and SLPI and elafin serine protease inhibitors all influence its expression.
Periodontitis, an oral disease which leads to alveolar bone loss, can be mediated by some of the endogenous host enzymes, as well as bacterial proteinases present in the periodontal pocket (e.g., neutrophil serine proteinase 3), mast cell tryptase, and gingipain from Porphyromonas gingivalis.
