Specificity of ferulic acid (feruloyl) esterases.
Specificity of ferulic acid (feruloyl) esterases G. Williamson’, C. B. Faulds and P. A. Kroon Biochemistry Department, Institute of Food Research, Norwich Research Park, Colney, Norwich NR4 7UA, U.K. 205 moyl esters (manifest as a K,,, of between lop6 Feruloyl esterases are a subclass of the carboxylic ester hydrolases (EC 3.1.1.1) which hydrolyse ester linkages between hydroxycinnamates and su...
متن کاملSpecificity of esterases. III. Critical concentrations of the substrate.
On the basis of this plot it was found (1) that, with a preparation of hog pancreas as the source of esterase, an apparent deviation from theoretical behavior was the result of the simultaneous action of two enzymes on the substrate. In the present investigation it is found that the curves obtained with horse liver esterase display two rather sharp discontinuities that cannot be ascribed to sim...
متن کاملSpecificity of esterases. I. Identification of two pancreatic aliesterases.
A plot of some linear relationship between reaction rate (v) and substrate concentration (S) is commonly used to estimate the constant,s of an enzyme system that follows the Michaelis-Menten theory of enzyme action. In cases in which there is certainty that only one enzyme is involved, it suffices to apply such a plot over a relatively short range of substrate concentrations. This certainty doe...
متن کاملSubstrate Recognition and Specificity of Chitin Deacetylases and Related Family 4 Carbohydrate Esterases
Carbohydrate esterases family 4 (CE4 enzymes) includes chitin and peptidoglycan deacetylases, acetylxylan esterases, and poly-N-acetylglucosamine deacetylases that act on structural polysaccharides, altering their physicochemical properties, and participating in diverse biological functions. Chitin and peptidoglycan deacetylases are not only involved in cell wall morphogenesis and remodeling in...
متن کاملOn the origins of esterases.
Comparisons among the primary sequences of five cloned eukaryotic esterases reveal two distinct lineages, neither bearing any significant overall sequence similarity to the functionally related serine protease multigene family. We have not eliminated the possibility that the esterases may have residual conformational similarities to the serine proteases. However, our profile analysis and analys...
