Efecto del pH en la actividad de fosfofructoquinasas tipo 2 de escherichia coli
(Universidad de Chile., 1989)
La cepa silvestre de E. coli contiene dos isoenzimas de fosfofructoquinasa; la forma principal, Pfk-1, responsable del 90-95% de las actividad fosfofrutoquinasica total y la forma minoritaria, Pfk-2. Ambas isoenzimas ...
Mecanismo cinético y regulación de fosfofructoquinasa-2 de escherichia coli : una mutante con propiedades alteradas
(Universisdad de Chile, 1985)
La cepa silvestre de E. coli contiene una fosfofructoquinasa
alostica, Pfk-1, la isoenzima principal y una isoenzima minoritaria,
Pfk-2, aparentemente no alostorica. La mutación pfkb aumenta los
niveles de Pfk-2, permite ...
Mecanismo cinético de fosfofructoquinasas tipo 2 de Escherichia coli
(Universisdad de Chile, 1984)
La cepa silvestre de E.coli contiene una fosfofructoquinasa alosterica, isoenzima principal, Pfk-1 y una isoenzima minoritaria,aparentemente no alosterica, Pfk-2 La mutación pfkB1 aumenta los niveles de Pfk-2, permite el ...
Influence of ligands on the aggregation of the normal and mutant forms of phosphofructokinase 2 of Escherichia coli
(1988)
The aggregation states of Escherichia coli phosphofructokinase 2 (Pfk-2) and of a mutant enzyme (Pfk-2*) altered in the inhibitory allosteric site for MgATP were measured in the presence and in the absence of substrates ...
Ribokinase family evolution and the role of conserved residues at the active site of the PfkB subfamily representative, Pfk-2 from Escherichia coli
(ELSEVIER SCIENCE INC, 2010-06-25)
Phosphofructokinase-2 (Pfk-2) belongs to the ribokinase family and catalyzes the ATP-dependent phosphorylation
of fructose-6-phosphate, showing allosteric inhibition by a second ATP molecule. Several
structures have been ...
The Entner–Doudoroff pathway empowers Pseudomonas putida KT2440 with a high tolerance to oxidative stress
(Wiley Blackwell Publishing, Inc, 2013-06)
Glucose catabolism of Pseudomonas putida is carried out exclusively through the Entner–Doudoroff (ED) pathway due to the absence of 6-phosphofructokinase. In order to activate the Embden–Meyerhof– Parnas (EMP) route we ...
Identification of a novel Pfkfb1 mRNA variant in rat fetal liver
(Elsevier, 2013-02)
The bifunctional enzyme 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase (PFK-2/FBPase-2) catalyzes the synthesis and degradation of fructose-2,6-bisphosphate, a key metabolite in the glucose homeostasis. Four genes, ...
ADP-dependent 6-Phosphofructokinase from Pyrococcus horikoshii OT3 STRUCTURE DETERMINATION AND BIOCHEMICAL CHARACTERIZATION OF PH1645
(AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY INC, 2009-06-24)
Some hyperthermophilic archaea use a modified glycolytic
pathway that employs an ADP-dependent glucokinase (ADPGK)
and an ADP-dependent phosphofructokinase (ADP-PFK)
or, in the case of Methanococcus jannaschii, a ...
