Structure and toxicity of a peptide hepatotoxin from the cyanobacterium Oscillatoria agardhii.
A peptide hepatotoxin was isolated by reversed phase liquid chromatography from the cyanobacterium Oscillatoria agardhii and characterized structurally and toxicologically. Amino acid analyses, proton nuclear magnetic resonance and fast atom bombardment mass spectrometry showed that the toxin is a cyclic heptapeptide (mol. wt 1023.5) with the structure cyclo-(Ala-Arg-Asp-Arg-Adda-Glu-N-methylde...
متن کاملBroad anti-HIV activity of the Oscillatoria agardhii agglutinin homologue lectin family.
OBJECTIVES Oscillatoria agardhii agglutinin homologue (OAAH) proteins belong to a recently discovered lectin family. The founding member OAA and a designed hybrid OAAH (OPA) recognize similar but unique carbohydrate structures of Man-9, compared with other antiviral carbohydrate-binding agents (CBAs). These two newly described CBAs were evaluated for their inactivating properties on HIV replica...
متن کاملStructural insights into the anti-HIV activity of the Oscillatoria agardhii agglutinin homolog lectin family.
Oscillatoria agardhii agglutinin homolog (OAAH) proteins belong to a recently discovered lectin family. All members contain a sequence repeat of ~66 amino acids, with the number of repeats varying among different family members. Apart from data for the founding member OAA, neither three-dimensional structures, information about carbohydrate binding specificities, nor antiviral activity data hav...
متن کاملSampling of Glycan-Bound Conformers by the Anti-HIV Lectin Oscillatoria agardhii agglutinin in the Absence of Sugar.
Lectins from different sources have been shown to interfere with HIV infection by binding to the sugars of viral-envelope glycoproteins. Three-dimensional atomic structures of a number of HIV-inactivating lectins have been determined, both as free proteins and in glycan-bound forms. However, details on the mechanism of recognition and binding to sugars are elusive. Herein we focus on the anti-H...
متن کاملPhosphate Uptake by Phosphate-Starved Euglena
Phosphate participates in an essential way in a number of cell functions, including glycolysis, oxidative phosphorylation, and nucleic acid synthesis. In almost all the cell types studied, the entry of phosphate seems to be controlled at the cell surface (1). In yeast, in which phosphate can be transported against a concentration gradient, the accumulation of phosphate depends on glycolysis and...
