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 ...

Hydrolytic enzymes are a large class of biological catalysts that play a vital role in a plethora of critical biochemical processes required to maintain human health. However, the expression and/or activity of these important enzymes can change in many different diseases and therefore represent exciting targets for the development of positron emission tomography (PET) and single-photon emission...

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 ...

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...

Mushrooms degrade lignocellulosic biomass by releasing lignolytic and hydrolytic enzymes which convert material into soluble low molecular weight compounds are then absorbed as nutrients. In the present study, enzymatic activities of Pleurotus HK 37 during growth on Saba comorensis exocarps were evaluated. It was observed that, has ability to produce enzyme (Laccase) (Carboxymethyl cellulase, x...
