Substrate specificity of the Chamaerops excelsa palm tree peroxidase. A steady-state kinetic study
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
The steady state kinetic mechanism of the H(2)O(2)-supported oxidation of different organic substrates by peroxidase from leaves of Chamaerops excelsa palm trees (CEP) has been investigated. An analysis of the initial rates ...
Biochemical and biophysical characterization of small heat shock proteins from sugarcane Involvement of a specific region located at the N-terminus with substrate specificity
(Pergamon-elsevier Science LtdOxfordInglaterra, 2007)
Specificity of human tissue kallikrein towards substrates containing Phe-Phe pair of amino acids
(Portland Press, 1999-04-15)
We have explored in detail the determinants of specificity for the hydrolysis by human tissue kallikrein (hK(1)) of substrates containing the Phe-Phe amino acid pair, after which hK(1) cleaves kallistatin (human ...
Subsites of trypsin active site favor catalysis or substrate binding
(Elsevier B.V., 2002-01-11)
Enzymes enhance chemical reaction rates by lowering the activation energy, the energy barrier of the reaction leading to products. This occurs because enzymes bind the high-energy intermediate of the reaction (the transition ...
Subsite substrate specificity of midgut insect chymotrypsins
(Elsevier B.V., 2008-06-01)
Insect chymotrypsins are distinctively sensitive to plant protein inhibitors, suggesting that they differ in subsite architecture and hence in substrate specificities. Purified digestive chymotrypsins from insects of three ...
ZapA, a possible virulence factor from Proteus mirabilis exhibits broad protease substrate specificity
(Associação Brasileira de Divulgação Científica, 2001-11-01)
The opportunistic bacterium Proteus mirabilis secretes a metalloprotease, ZapA, considered to be one of its virulence factors due to its IgA-degrading activity. However, the substrate specificity of this enzyme has not yet ...
Development of an operational substrate for ZapA, a metalloprotease secreted by the bacterium Proteus mirabilis
(Associação Brasileira de Divulgação Científica, 2000-07-01)
The protease ZapA, secreted by Proteus mirabilis, has been considered to be a virulence factor of this opportunistic bacterium. The control of its expression requires the use of an appropriate methodology, which until now ...
