“…Surfactants such as Tween 80 that accumulate at the interphase reduce the interfacial tension and lead to prevention of enzyme activityan effect that seems to be not restricted to proteases but also holds for lipases . Recent mechanistic studies using papain as the catalyst led to a model that allows the prediction of the enzyme stability in such biphasic systems with a correlation coefficient of 0.829 between the model and the experimental data . From the same laboratory, an approach has been developed for predicting changes of the aqueous phase pH on the basis of the partition of reaction substrates in biphasic systems which has been shown to be useful for selecting optimum reaction conditions .…”

“…24 Recent mechanistic studies using papain as the catalyst led to a model that allows the prediction of the enzyme stability in such biphasic systems with a correlation coefficient of 0.829 between the model and the experimental data. 25 From the same laboratory, an approach has been developed for predicting changes of the aqueous phase pH on the basis of the partition of reaction substrates in biphasic systems which has been shown to be useful for selecting optimum reaction conditions. 26 Further recently published papers document the successful application of such biphasic systems for other proteases such as cardosins A and B 27 or thermolysin, 28 but also for other enzymes such as amine oxidases, 29 immobilized beta-glycosidase, 30 chloroperoxidase, 31 P-galactosidase from Aspergillus oryzae, 32 penicillin acylase, 33 and many others.…”

“…No entanto, para que 0,4 U/mg de proteína fosse obtido para a papaína A, uma quantidade 7 vezes maior de matéria-prima foi utilizada em comparação à papaína B. Este resultado evidencia a importância da caracterização de matérias-primas macromoleculares pela medida das quantidades de atividade biológica e de proteína por grama de matéria-prima. CLELAND, 1995;FAN et al, 2001;SANCHEZ-RUIZ;MAKATDZE, 2001). Outra vantagem de se utilizar gel hidrofílico para veicular proteínas é a hidrossolubilidade dessas macromoléculas (MORISHITA et al, 2001).…”

“…Para llevar a cabo esta síntesis en los últimos años se está utilizando con éxito a las proteasas. Actualmente, la aplicación de proteasas en la producción de pequeños péptidos, ha recibido mucha atención ya que constituye una alternativa viable a la síntesis química (Fan et al, 2001).…”
