Crystallization and preliminary X-ray diffraction analysis of a novel sphingomyelinase D from Loxosceles gaucho venom
(Acta Crystallographica Section F-structural Biology Communications, 2014-10-01) [Artigo]
Brown spider envenomation results in dermonecrosis, intravascular coagulation, haemolysis and renal failure, mainly owing to the action of sphingomyelinases D (SMases D), which catalyze the hydrolysis of sphingomyelin to ...
Crystallization and preliminary X-ray diffraction studies of an L-amino-acid oxidase from Lachesis muta venom
(Acta Crystallographica Section F-structural Biology Communications, 2014-11-01) [Artigo]
Snake-venom proteins form multi-component defence systems by the recruitment and rapid evolution of nonvenomous proteins and hence serve as model systems to understand the structural modifications that result in toxicity. ...
Purification and biochemical characterization of an alkaline pectin lyase from Fusarium decemcellulare MTCC 2079 suitable for Crotolaria juncea fiber retting
(Journal Of Basic Microbiology, 2014-07-01) [Artigo]
An extracellular pectin lyase secreted by Fusarium decemcellulare MTCC 2079 under solid state fermentation condition has been purified to electrophoretic homogeniety by using ammonium sulfate fractionation, carboxymethyl ...
Molecular model for the binary complex of uropepsin and pepstatin
(Biochemical and Biophysical Research Communications, 2001-09-14) [Artigo]
The three-dimensional structure of human uropepsin complexed with pepstatin has been modelled using human pepsin as a template. Uropepsin is an aspartic proteinase from the urine, produced in the form of pepsinogen A in ...
Comments on Interfacial lateral electrical conductance on lipid monolayers: Dose-dependent converse effect of alcohols, by Yoshida, T., Koga, Y., Minowa, H., kamaya, H., and Ueda, I.
(Journal of Physical Chemistry B, 2001-01-18) [Artigo]
Supersymmetric and shape-invariant generalization for nonresonant and intensity-dependent Jaynes-Cummings systems
(Journal of Physics A: Mathematical and General, 2001-02-16) [Artigo]
A class of shape-invariant bound-state problems which represent transitions in a two-level system introduced earlier are generalized to include arbitrary energy splittings between the two levels as well as intensity-dependent ...
Molecular models for shikimate pathway enzymes of Xylella fastidiosa
(Biochemical and Biophysical Research Communications, 2004-07-30) [Artigo]
The Xylella fastidiosa is a bacterium that is the cause of citrus variegated chlorosis (CVC). The shikimate pathway is of pivotal importance for production of a plethora of aromatic compounds in plants, bacteria, and fungi. ...
Structural basis for inhibition of human PNP by immucillin-H
(Biochemical and Biophysical Research Communications, 2003-10-03) [Artigo]
Purine nucleoside phosphorylase (PNP) catalyzes the phosphorolysis of the N-ribosidic bonds of purine nucleosides and deoxynucleosides. PNP is a target for inhibitor development aiming at T-cell immune response modulation. ...
Structures of human purine nucleoside phosphorylase complexed with inosine and ddI
(Biochemical and Biophysical Research Communications, 2004-01-23) [Artigo]
Human purine nucleoside phosphorylase (PNP) is a ubiquitous enzyme which plays a key role in the purine salvage pathway, and PNP deficiency in humans leads to an impairment of T-cell function, usually with no apparent ...
New catalytic mechanism for human purine nucleoside phosphorylase
(Biochemical and Biophysical Research Communications, 2005-02-18) [Artigo]
Human purine nucleoside phosphorylase has been submitted to intensive structure-based design of inhibitors, most of them using low-resolution structures of human PNP. Recently, several structures of human PNP have been ...
