GAP is part of the quorum sensing system of certain bacteria where it positively regulates the expression of gelatinase and serine proteases that are under the control of the gelE-sprE operon.
32.
There is often a greyish discoloration around the colonies on blood agar due to proteases and gelatinase . " E . meningoseptica " grow poorly on MacConkey agar and are considered glucose oxidizers.
33.
"' Gelatinase biosynthesis-activating pheromone "'abbreviated as "'GBAP "'is a cyclic peptide produced by pathogenic bacteria such as " Enterococcus faecalis ".
34.
Revised model for Enterococcus faecalis fsr quorum-sensing system : the small open reading frame fsrD encodes the gelatinase biosynthesis-activating pheromone propeptide corresponding to staphylococcal agrD . J . Bacteriol . 1888321-8326.
35.
It does not produce oxidase, coagulase, clumping factor, fibrinolysin, thermostable nuclease, tellurite reductase, gelatinase, protease, urease, arginine dihydrolase, alpha-or beta-haemeolysins, ornithine decarboxylase, acetyl-methylcarbinol, or beta-galactosidase.
36.
One study suggests the drug amplifies production of neutrophil gelatinase-associated lipocalin ( NGAL ) in the skin, which has been shown to reduce sebum production by inducing apoptosis in sebaceous gland cells, while exhibiting an antimicrobial effect on " Propionibacterium acnes ".
37.
"Brevibacillus brevis " forms Gram-positive ( variable ) rods with optimal growth of 35-55�C . It is a motile spore-former with positive catalase activity, amylase negative, casein negative, gelatinase positive, and indole negative, and most are citrate users.
38.
When " P . vulgaris " is tested using the API 20E identification system it produces positive results for sulfur reduction, urease production, tryptophan deaminase production, indole production, sometimes positive gelatinase activity, and saccharose fermentation, and negative results for the remainder of the tests on the testing strip.
39.
"' Neutrophil-specific granule deficiency "'( "'SGD "', previously known as "'lactoferrin deficiency "') is a rare congenital immunodeficiency characterized by an increased risk for pyogenic infections due to defective production of specific granules and gelatinase granules in patient neutrophils.
40.
Isotretinoin has been speculated to down-regulate the telomerase enzyme and hTERT, inhibiting " tumorigenesis . " In a 2007 study, Isotretinoin was proven to inhibit the action of the metalloprotease MMP-9 ( gelatinase ) in sebum without any influence in the action of TIMP1 and TIMP2 ( the tissue inhibitors of metalloproteases ).
