Síntese e ativação superficial de novos suportes magnéticos para imobilização de enzimas
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Biotecnologia - PPGBiotec, 2013-10-16)
Enzymes are potent catalysts, but operationally fragile, expensive and soluble. Industrial applications of enzymes, often, are possible only using immobilized enzyme. Nowadays, various studies have been performed aiming ...
Caracterização estrutural e funcional de uma xiloglucanase de Xanthomonas campestris
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Biotecnologia - PPGBiotec, 2013-07-25)
Xyloglucanases (Xghs) are important enzymes involved in xyloglucan modification and degradation. Xanthomonas campestris (Xcc) is a phytopathogenic bacterium which produces a large number of glycosyl hydrolases (GH), but ...
Inibição enzimática analisada com uma abordagem da mecânica estatística
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2019-02-21)
In the conventional approach of Biochemistry, a parameter for the description of the functioning of an enzyme is the rate of conversion of substrate into product in the presence or absence of an inhibitor. Given this ...
