Crude venom contained gelatinase
activity up to dilutions of 1/2.
Traits that may enhance the virulence include the usual suspects cytolysin, aggregation substance, adhesions, extracellular superoxide (ESO), extracellular surface protein (ESP), haemolysin and gelatinase
Latent and active forms of gelatinase
A were characterized from guanidine HC1 extracts of rat cervixes from non-pregnant rats, and pregnant rats at day 11, 17, term and 4 days post partum using gel zymography and/or western blot analyses (1, 2).
The phenotypic determination of possible virulence factors showed that the isolates (VP1-VP3 and VR1-VR3) all produced [beta]-hemolysis on rabbit blood agar, lecithinase, proteinase, gelatinase
, and DNase.
This increased pressure phenomenon apparently leads to osteoclastic activation for resorption of bone, presumably from the elevated cytokines (prostaglandins, (13) interleukin 1[beta], and gelatinase
(14)) released by the endothelial cells lining the cyst wall.
The results show that both the 62kD collagenase and the 92kD gelatinase
have increased activity in obese kidneys.
That research led us to discover an enzyme called gelatinase
that played a role in the turnover of the articular cartilage.
Doxycycline is thought to inhibit gelatinase
, which breaks down components of the skin's extracellular matrix.
The Chanel laboratories have developed an ultra-targeted formula called Precision Age Delay Eye, which combines extract, of horse chestnut with a marine polysaccharide (a powerful inhibitor of gelatinase
A, an enzyme said to play a key role in the aging of the eye area), and a lipopeptide, also used in the Age Delay serum for the face.
mannitol motility test, indole production test, urease test, citrate utilization, methyl red test, voges-proskauer's test, catalase test, oxidase test, nitrate reduction test, aminoacid utilization test, test for production of amylase, caseinase, dnase, sugar utilization test, phenylalanine deaminase test, cellulase test, ONPG (P-galactosidase enzyme), gelatinase

The isolation, characterization, and molecular cloning of a 75-kDa gelatinase
B-like enzyme, a member of the matrix metalloproteinase (MMP) family.
SalA showed selectivity on gelatinase
(MMP-2 and MMP-9) than on collagenase (MMP-8 and MMP-13) in vitro, and specificity on MMP-9 than MMP-2 in vivo.
