Schiff bases of poly-L-lysine and some compounds of the vitamin B-6 group. Influence of polypeptidic structure
(ELSEVIER SCIENCE BV, 1997)
The apparent rate constants of formation (k(1)) and hydrolysis (k(2)) of the Schiff bases formed between pyridoxal and poly-L-lysine has been fitted to a kinetic scheme that involves the different protonated species in the ...
DETERMINATION OF THE RATES OF FORMATION AND HYDROLYSIS OF THE SCHIFF-BASES FORMED BY PYRIDOXAL AND POLY-L-LYSINE
(ELSEVIER SCIENCE BV, 1994)
The rate constants of formation (k1ex) and hydrolysis (k2) of the Schiff bases of pyridoxal (PL) with poly-L-lysine were determined as a function of pH at a temperature of 25-degrees-C and an ionic strength I=0.1 M. The ...
Catalytic and regulatory roles of species involved in metal–nucleotide equilibriums in human pyridoxal kinase
(Springer, 2013)
Pyridoxal 50-phosphate is the active form
of vitamin B6 and its deficiency is directly related with
several human disorders, which make human pyridoxal
kinase (hPLK) an important pharmacologic
target. In spite of this, ...
An Evolutionary Marker of the Ribokinase Superfamily Is Responsible for Zinc-Mediated Regulation of Human Pyridoxal Kinase
(MDPI, 2020)
The ribokinase superfamily catalyzes the phosphorylation of a vast diversity of substrates, and its members are characterized by the conservation of a common structural fold along with highly conserved sequence motifs ...
DETERMINATION OF THE RATES OF FORMATION AND HYDROLYSIS OF THE SCHIFF-BASES OF PYRIDOXAL WITH POLYALLYLAMINE
(ELSEVIER SCIENCE BV, 1995)
The rate constants of formation (k(1)) and hydrolysis (k(2) of the Schiff bases formed between pyridoxal (PL) and polyallylamine were determined as a function of pH at a temperature of 25 degrees C and an ionic strength ...
DETERMINATION OF THE RATES OF FORMATION AND HYDROLYSIS OF THE SCHIFF-BASES FORMED BY PYRIDOXAL 5'-PHOSPHATE AND COPOLYPEPTIDES CONTAINING L-LYSINE
(ELSEVIER SCIENCE BV, 1993)
We determined the apparent rate constants of formation (k1) and hydrolysis (k2) of the Schiff bases formed between pyridoxal 5'-phosphate (PLP) and L-lysine and L-alanine copolymers of different compositions, as well as ...
Synthesis, structure and SOD activity of Mn complexes with symmetric Schiff base ligands derived from pyridoxal
(Elsevier, 2015-09)
This study describes the synthesis, crystal structure and antioxidant activity of manganese(III) complexes with Schiff-base ligands obtained from condensation of pyridoxal with alkyl diamines: [Mn(pyr2en) (H2O)2]Cl 4H2O, ...
Síntese, análise estrutural e avaliação da atividade catalítica mimética da superóxido dismutase e peroxidases de complexos derivados do piridoxal e cobre
(Universidade Federal de Santa MariaBRQuímicaUFSMPrograma de Pós-Graduação em Química, 2016-03-31)
This work presents the synthesis and characterization of copper complexes
that mimic the activity of the superoxide dismutase enzyme, which operates in the
elimination of reactive oxygen species or in the activation of ...
On the l-dopa and carbidopa reactivity against pyridoxal 5-phosphate. A kinetic study
(NIHON KAGAKKAI, 2002)
