Hydrolytic enzymes of Moraxella bovis.
Certain strains of Moraxella bovis produce tissue-damaging enzymes which may initiate or potentiate infectious bovine keratoconjunctivitis. Thirteen reference strains of this species were characterized physiologically and screened for production of various enzymes by some conventional biochemical tests and the API ZYM system (Analytab Products, Plainview, N.Y.). All 13 strains were hemolytic. A...
متن کاملHydrolytic Enzymes of Rabbit Mononuclear Exudate Cells
Oil-induced mononuclear phagocytes (MN) were quantitatively assayed for various hydrolases as unfractionated suspensions of frozen and thawed cells. They apparently contain two proteases. The first, measured with urea- or acid-denatured hemoglobin, was similar to purified Proteinase I of lung with respect to pH optimum (pH 4), stability, hydrolytic and polymerizing activities, and reactions to ...
متن کاملHydrolytic enzymes in Paracoccidioides brasiliensis--ecological aspects.
Paracoccidioides brasiliensis is a thermally dimorphic fungus that causes paracoccidioidomycosis. The yeast form of this pathogen is found in the animal host whereas the mycelial form is recovered from living and non-living organic material. The sole carbon source available in these habitats is represented by polysaccharides from the plant cell wall. Hydrolytic enzymes are necessary to convert ...
متن کاملUseful hydrolytic enzymes: Proteases, lipases and nitrilases
The most recent developments in the use of hydrolytic enzymes proteases, lipases and nitrilases are summarized: Sterically demanding a,a-disubstituted carboxylic esters can be enzymatically resolved using a commercially available protease derived from Aspergillus oryzae. A significant enhancement of selectivity and activity of Candida cylindracea lipase in irreversible acyl transfer reactions m...
متن کاملThe inhibition of hydrolytic enzymes by organophosphorus compounds.
It has been shown that several hydrolytic enzymes with different specificities undergo similar reactions with diisopropyl phosphorofluoridate (1) and other related toxic organophosphorus compounds (2). These conclusions were based on kinetic studies, particularly the influence of pH on the rates of reaction, and on inhibition characteristics. Reactions of this type have provided a unique method...
