Nitrilase Catalyzes Amide Hydrolysis as Well as Nitrile Hydrolysis
Biochemical and Biophysical Research Communications, 1998While amides were reported to be completely inert as substrates for all nitrilases reported to date, the nitrilase from Rhodococcus rhodochrous J1, which catalyzes the hydrolytic cleavage of the C-N triple bond in nitrile to form acid and ammonium, was surprisingly found to catalyze hydrolysis of amide to acid and ammonium stoichiometrically.

Hydrolysis of esters by staphylococci
International Journal of Food Microbiology, 1997The objective of this work was to characterize the hydrolysis of esters by staphylococci in order to understand if they could contribute to the release of free fatty acids in sausage. Cell-free extracts and extracellular concentrates of staphylococci were examined for esterase activities against p-nitrophenyl esters and for lipolytic activities against

Hydrolysis and protection from hydrolysis of enkephalins in human plasma
Neurochemical Research, 1990Seven groups of enkephalin-degrading enzymes and three groups of inhibitors active on these enzymes were separated from human plasma. The activity of the enzymes in hydrolyzing enkephalins and of the inhibitors in protecting enkephalins from proteolysis was measured.

The glycosidic bond might be degraded by chemical and/or enzymatic agents. Comparative studies revealed that chemical hydrolysis is nonspecific and on the other hand the enzymatic is regiospecific and stereospecific. The glycosides are chemically susceptible to acid conditions and only in some cases to basic conditions.

Abstract There are two general approaches to the use of hydrolysis and esterification in asymmetric synthesis, and usually both involve the use of enzymes as asymmetric catalysts. In one case the asymmetric catalyst is used in a kinetic resolution process in which one enantiomer of a racemic mixture reacts more rapidly than its antipode.
