A new amperometric biosensor for fructose using a carbon paste electrode modified with silica gel coated with Meldola's Blue and fructose 5-dehydrogenase
(Elsevier Science Sa LausanneLausanneSuíça, 1996)
Enzyme immobilization on Ag nanoparticles/polyaniline nanocomposites
(ELSEVIER ADVANCED TECHNOLOGY, 2009)
We show a simple strategy to obtain all efficient enzymatic broelectrochemical device, in which urease was immobilized oil electroactive nanostructured membranes (ENMs) made with polyaniline and silver nanoparticles (AgNP) ...
Modification of the amaranth 11S globulin storage protein to produce an inhibitory peptide of the angiotensin I converting enzyme, and its expression in Escherichia coli
(2013-01-29)
Amarantin is the predominant seed storage protein from amaranth. It shows a high content of essential amino acids, making this protein important from a nutritional viewpoint. The protein has two disulfide linked subunits: ...
EFFECT OF CULTIVATION CONDITIONS ON GLUCOSE-6-PHOSPHATE DEHYDROGENASE PRODUCTION BY GENETICALLY MODIFIED Saccharomyces cerevisiae
(BRAZILIAN SOC CHEMICAL ENG, 2009)
The objective of this research was to improve Glucose-6-phosphate dehydrogenase (G6PD) production by Saccharomyces cerevisiae W303-181, which carry the plasmid YEpPGK-G6PD, by varying the following cultivation conditions: ...
Enzyme mimic of heterobimetallic Cu(II) and Fe(III) tetrapyridylporphine modified nanoparticles
(Elsevier Science, 2011-12)
The covalent binding of the porphyrin to immobilized gold nanoparticles resulted in a very useful and simple method to evaluate the absorption spectroscopy of a monolayer of porphyrins and the spectral changes produced by ...
Structural and functional roles of Cys-238 and Cys-295 in Escherichia coli phosphofructokinase-2
(2003)
Modification of Escherichia coli phosphofructokinase-2 (Pfk-2) with pyrene maleimide (PM) results in a rapid inactivation of the enzyme. The loss of enzyme activity correlates with the incorporation of 2 mol of PM/mol of ...
Optimizing aminoglycoside selection for KPC-producing Klebsiella pneumoniae with the aminoglycoside-modifying enzyme (AME) gene aac(6')-Ib
(Oxford University Press, 2021)
OBJECTIVES: KPC-producing Klebsiella pneumoniae (KPC-Kp) isolates commonly co-harbour the aminoglycoside-modifying enzyme (AME) gene aac(6')-Ib, which encodes an AME that can confer resistance to some of the commercially ...
Production of active recombinant eIF5A: reconstitution in E. coli of eukaryotic hypusine modification of eIF5A by its coexpression with modifying enzymes
(2011)
Eukaryotic translation initiation factor 5A (eIF5A) is the only cellular protein that contains the polyamine-modified lysine, hypusine [Nε-(4-amino-2-hydroxybutyl)lysine]. Hypusine occurs only in eukaryotes and certain ...
Amperometric biosensor for lactate based on Meldola's blue adsorbed on silica gel modified with niobium oxide
(Wiley-v C H Verlag GmbhWeinheimAlemanha, 2006)
