Purification and characterisation of a fructosyltransferase from Rhodotorula sp.
(SpringerNew YorkEUA, 2008)
Crystal structure of Jararacussin-I: The highly negatively charged catalytic interface contributes to macromolecular selectivity in snake venom thrombin-like enzymes
Snake venom serine proteinases (SVSPs) are hemostatically active toxins that perturb the maintenance and regulation of both the blood coagulation cascade and fibrinolytic feedback system at specific points, and hence, are ...
Produção de glicose e frutose por invertase de Saccharomyces cerevisiae imobilizada em suporte MANAE-agarose
Invertase from Saccharomyces cerevisiae was immobilized on agarose beads, activated with various groups (glyoxyl, MANAE or glutaraldehyde), and on some commercial epoxy supports (Eupergit and Sepabeads). Very active and ...
Effect of early feed restriction and enzyme supplementation on digestive enzyme activities in broilers
(Poultry Science Assoc Inc, 2014)
Extracellular β-fructofuranosidase from Fusarium graminearum: Stability of the spray-dried enzyme in the presence of different carbohydrates
Microbial enzymes have been used for various biotechnological applications; however, enzyme stabilization remains a challenge for industries and needs to be considered. This study describes the effects of spray-drying ...
The zymogen-enteropeptidase system: A practical approach to study the regulation of enzyme activity by proteolytic cleavage
(Amer Soc Biochemistry Molecular Biology Inc, 2004-01-01)
The present research describes an efficient procedure to obtain high levels of trypsinogen and chymotrypsinogen by using a simple, rapid, and easily reproducible method. The extraction process and the time-course of ...
Lipid Metabolizing Enzyme Activities Modulated by Phospholipid Substrate Lateral Distribution
Biological membranes contain many domains enriched in phospholipid lipids and there is not yet clear explanation about how these domains can control the activity of phospholipid metabolizing enzymes. Here we used the surface ...
Are levels of digestive enzyme activity related to the natural diet in passerine birds?
(Sociedad de Biología de Chile, 2011)
Cellulolytic activity of wild type and mutant Trichoderma pseudokoningii
Strains of Trichoderma pseudokoningii are promising objects for genetic studies and cellulase production. Auxotrophic mutants with deficiencies in the biosynthesis of aminoacids, nucleotides and vitamins (up to five markers) ...
