In silico identification of noncompetitive inhibitors targeting an uncharacterized allosteric site of falcipain-2
(2021-01-01)
Falcipain-2 (FP-2) is a Plasmodium falciparum hemoglobinase widely targeted in the search for antimalarials. FP-2 can be allosterically modulated by various noncompetitive inhibitors that have been serendipitously identified. ...
The water effect on the kinetics of the bovine liver catalase
(2011-09-01)
Catalase is an enzyme that occurs in almost all aerobic organisms. Its main metabolic function is to prevent oxidative damage to tissues induced by hydrogen peroxide which is a strong oxidizing agent. Catalase is very ...

Order-Disorder Transitions Govern Kinetic Cooperativity and Allostery of Monomeric Human Glucokinase
(PUBLIC LIBRARY SCIENCESAN FRANCISCO, 2012)
Glucokinase (GCK) catalyzes the rate-limiting step of glucose catabolism in the pancreas, where it functions as the body's principal glucose sensor. GCK dysfunction leads to several potentially fatal diseases including ...
Computational study on the allosteric mechanism of Leishmania major IF4E-1 by 4E-interacting protein-1: Unravelling the determinants of m7GTP cap recognition
(2021-01-01)
During their life cycle, Leishmania parasites display a fine-tuned regulation of the mRNA translation through the differential expression of isoforms of eukaryotic translation initiation factor 4E (LeishIF4Es). The interaction ...
Molecular motions as a drug target: mechanistic simulations of anthrax toxin edema factor function led to the discovery of novel allosteric inhibitors
(MDPI AGBasel, 2012-08)
Edema Factor (EF) is a component of Bacillus anthracis toxin essential for virulence. Its adenylyl cyclase activity is induced by complexation with the ubiquitous eukaryotic cellular protein, calmodulin (CaM). EF and its ...
Structure and function of crocodilian hemoglobins and allosteric regulation by chloride, ATP, and CO2
(American Physiological Society, 2020-03)
Hemoglobins (Hbs) of crocodilians are reportedly characterized by unique mechanisms of allosteric regulatory control, but there are conflicting reports regarding the importance of different effectors, such as chloride ions, ...
Understanding the molecular basis of the high oxygen affinity variant human hemoglobin Coimbra
(Elsevier Science Inc, 2018-01)
Human hemoglobin (Hb) Coimbra (βAsp99Glu) is one of the seven βAsp99 Hb variants described to date. All βAsp99 substitutions result in increased affinity for O2 and decreased heme-heme cooperativity and their carriers are ...
Inibição enzimática analisada com uma abordagem da mecânica estatística
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2019-02-21)
In the conventional approach of Biochemistry, a parameter for the description of the functioning of an enzyme is the rate of conversion of substrate into product in the presence or absence of an inhibitor. Given this ...
