Extracellular enzymes of Legionella pneumophila.
All strains of Legionella pneumophila tested produced detectable levels of extracellular protease, phosphatase, lipase, deoxyribonuclease, ribonuclease, and beta-lactamase activity. Weak starch hydrolysis was also demonstrated for all strains. Elastase, collagenase, phospholipase C, hyaluronidase, chondroitinase, neuraminidase, or coagulase were not detected in any of these laboratory-maintaine...
متن کاملThe extracellular enzymes of Coniophora cerebulla.
1. The extracellular enzymes present in the culture filtrates of Coniophora cerebella grown on various carbohydrate carbon sources were investigated. Enzymes that degraded cellulose derivatives, hemicellulose fractions, starch, laminarin, pectin and several oligosaccharides were detected. 2. All the polysaccharide-degrading activities were adaptive except for that acting on laminarin. 3. The cu...
متن کاملRelease of extracellular enzymes from Bacillus amyloliquefaciens.
Washed-cell suspensions of Bacillus amyloliquefaciens secrete significant amounts of the extracellular enzymes alpha-amylase and protease for about 15 min in the almost complete absence of protein synthesis. This apparently represents release of preformed enzyme en route to secretion. The release was independent of energy but was affected by temperature. Pulse-labeling experiments showed that n...
متن کاملExtracellular enzymes of the genus Bacteroides.
The extracellular production of hyaluronidase and chondroitin sulfatase was demonstrated in all of the subspecies of Bacteroides fragilis tested with the exception of B. fragilis subsp. vulgatus. Elastase was found only in one strain of B. coagulans tested. This appears to be the first report of these enzyme activities in this genus. Additional enzymes found to be produced by certain members ot...
متن کاملMycobacteria Exploit Host Hyaluronan for Efficient Extracellular Replication
In spite of the importance of hyaluronan in host protection against infectious organisms in the alveolar spaces, its role in mycobacterial infection is unknown. In a previous study, we found that mycobacteria interact with hyaluronan on lung epithelial cells. Here, we have analyzed the role of hyaluronan after mycobacterial infection was established and found that pathogenic mycobacteria can gr...
