(2020)
This thesis presents the synthesis and characterization of a series of both monometallic coordination compounds and homo-nuclear bimetallic helicates, derived from Fe(II), Zn(II) and Cu(I), with bi-coordinating and ...
Mejoramiento de la fertilización fosfatada en la asociación ryegrass y trébol rojo mediante el uso de bacterias solubilizadoras de fosfato
(Bogotá - Ciencias - Maestría en Ciencias - MicrobiologíaUniversidad Nacional de Colombia - Sede Bogotá, 2020-07-29)
In Colombia, specialized tropical highland dairy production systems are supported by pastures, which they are located in higher altitudes to 2200 meters above sea level and generate 70% of the national dairy production. ...
Sinorhizobium meliloti low molecular mass phosphotyrosine phosphatase SMc02309 modifies activity of the UDP-glucose pyrophosphorylase ExoN involved in succinoglycan biosynthesis
(SP MAIK Nauka/Interperiodica, 2016-01)
In Gram-negative bacteria, tyrosine phosphorylation has been shown to play a role in the control of exopolysaccharide (EPS) production. This study demonstrated that the chromosomal ORF SMc02309 from Sinorhizobium meliloti ...
Estudo e desenvolvimento de estratégias de remoção de organofosforados de soluções aquosas utilizando sílicas porosas e policloreto de vinila
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE QUÍMICAPrograma de Pós-Graduação em QuímicaUFMG, 2020-11-11)
This work addresses the use of silicates and plastics in the removal of organophosphates from aqueous solutions. The studies were divided into three parts: 1. kinetic study of the hydrolysis of organophosphates by ...

Construction of an alkaline phosphatase-liposome system: a tool for biomineralization study
(Elsevier B.V., 2002-09-01)
Alkaline phosphatase is required for the mineralization of bone and cartilage. This enzyme is localized in the matrix vesicle, which plays a role key in calcifying cartilage. In this paper. we standardize a method for ...
Glucosidase II beta subunit modulates N-glycan trimming in fission yeasts and mammals
(American Society for Cell Biology, 2009-07)
Glucosidase II (GII) plays a key role in glycoprotein biogenesis in the endoplasmic reticulum (ER). It is responsible for the sequential removal of the two innermost glucose residues from the glycan (Glc(3)Man(9)GlcNAc(2)) ...
Assessment of neutralizing capacity of antibodies raised in mice against a Crotalus durissus terrificus phosphodiesterase
(Fundación Revista Medicina, 2019)
Phosphodiesterases (PDE) belong to a super-family of enzymes that have multiple roles in the metabolism of nucleotides. These enzyme classes have played such a critical role as tools in the field of molecular biology, but ...
Effect of nonionic surfactants on Rhizopus homothallicus lipase activity: A comparative kinetic study
(2007)
Based on amino-terminal sequencing and mass spectrometry data on the Rhizopus homothallicus lipase extracted using solid (SSF) and submerged state fermentation (SmF) methods, we previously established that the two enzymes ...
Imobilização da enzima β-galactosidase de Kluyveromyces fragilis em agarose e quitosana utilizando diferentes protocolos de ativação
