An asymmetric substrate-controlled Morita-Baylis-Hillman reaction as approach for the synthesis of pyrrolizidinones and pyrrolizidines
(Pergamon-elsevier Science LtdOxfordInglaterra, 2014)
Characterization of human sperm N-acetylglucosaminidase
(Wiley Blackwell Publishing, Inc, 2008-06)
N-acetylglucosaminidase (NAG) is particularly active in mammalian spermatozoa and appears to be involved in fertilization. Although it is assumed that this enzyme is acrosomal, previous results from our laboratory suggest ...
Intestinal α-glycosidase transcriptional responses during development and diet adjustment in altricial birds
(Company of Biologists, 2018-03)
We describe developmental changes in maltasic activity and its mRNA until adulthood, and in response to an increase in dietary starch. We studied house sparrows (Passer domesticus), which undergo a natural switch from ...
α-L-Arabinofuranosidase activity during development and ripening of normal and ACC synthase antisense tomato fruit
(American Society for Horticultural Science, 2002-12)
α-L-Arabinofuranosidases (α-Af) are plant enzymes that have the capacity to release terminal arabinofuranosyl residues from a wide variety of pectic and hemicellulosic polymers, as well as different glycoconjugates. Our ...
A new application of humic substances: Activation of supports for invertase immobilization
(2000-12-01)
Invertase was immobilized on aminopropyl silica (APTS-SiO2) activated with humic substances (APTS-SiO2-HS) and on aminopropyl silica activated with glutaraldehyde (APTS-SiO2-GA). The resulting activity of both systems was ...

Molecular identification of a cyclodextrin glycosyltransferase-producing microorganism and phylogenetic assessment of enzymatic activities
(Academia Brasileira de Ciências, 2019-10)
Cyclodextrin glycosyltransferases (CGTases) are important enzymes in the biotechnology field because they catalyze starch conversion into cyclodextrins and linear oligosaccharides, which are used in food, pharmaceutical ...
