Journal ArticleDOI
Modulation by ammonium ions of gill microsomal (Na+,K+)-ATPase in the swimming crab Callinectes danae: a possible mechanism for regulation of ammonia excretion
D. C. Masui,Rosa dos Prazeres Melo Furriel,John Campbell McNamara,Fernando L. Mantelatto,Francisco A. Leone +4 more
TL;DR: Ammonium and potassium ions synergistically stimulated the enzyme, increasing specific activities up to 90%, suggesting that these ions bind to different sites on the molecule.
Journal ArticleDOI
Purification and biochemical characterization of a mycelial glucose- and xylose-stimulated β-glucosidase from the thermophilic fungus Humicola insolens
Flavio Henrique Moreira Souza,César Vanderlei Nascimento,José César Rosa,D. C. Masui,Francisco A. Leone,João Atílio Jorge,Rosa dos Prazeres Melo Furriel +6 more
TL;DR: A mycelial β-glucosidase from the thermophilic mold Humicola insolens was purified and biochemically characterized in this paper, and the enzyme showed carbohydrate content of 21% and apparent molecular mass of 94 kDa, as estimated by gel filtration.
Journal ArticleDOI
Optimization of β-glucosidase, β-xylosidase and xylanase production by Colletotrichum graminicola under solid-state fermentation and application in raw sugarcane trash saccharification.
Ana Lucia Ribeiro Latorre Zimbardi,Cesar Sehn,Luana Parras Meleiro,Flavio Henrique Moreira Souza,D. C. Masui,Monica Stropa Ferreira Nozawa,Luis Henrique Souza Guimarães,João Atílio Jorge,Rosa dos Prazeres Melo Furriel +8 more
TL;DR: The production of β-glucosid enzyme, β-xylosidase and xylanase by Colletotrichum graminicola was optimized using Response Surface Methodology (RSM), demonstrating good potential to compose efficient cocktails for lignocellulosic materials hydrolysis.
Journal ArticleDOI
Purification and biochemical properties of a glucose-stimulated β-D-glucosidase produced by Humicola grisea var. thermoidea grown on sugarcane bagasse
César Vanderlei Nascimento,Flavio Henrique Moreira Souza,D. C. Masui,Francisco A. Leone,Rosane Marina Peralta,João Atílio Jorge,Rosa dos Prazeres Melo Furriel +6 more
TL;DR: Findings suggest that H. grisea var.
Journal ArticleDOI
Effect of molecular surface packing on the enzymatic activity modulation of an anchored protein on phospholipid Langmuir monolayers.
Luciano Caseli,Rafael G. Oliveira,D. C. Masui,Rosa dos Prazeres Melo Furriel,Francisco A. Leone,Bruno Maggio,M. Elisabete D. Zaniquelli +6 more
TL;DR: A model for the modulation of the enzyme orientation and catalytic activity by lipid/enzyme surface morphology and enzyme surface packing at the air/liquid interface is proposed and might have an important impact on the comprehension of the enzymatic activity regulation of GPI-anchored proteins in biomembranes.
