Isolation and characterization of four toxins from the blue-green alga, Microcystis aeruginosa.
Two alternative procedures for the isolation of toxins from the blue-green alga, Microcystis aeruginosa forma aeruginosa, are described. A novel approach is reported, whereby contaminating impurities
The structure of cyanoginosin-LA, a cyclic heptapeptide toxin from the cyanobacterium Microcystis aeruginosa
The structure of cyanoginosin-LA (previously referred to by us as toxin BE-4) is cyclo(-D-Ala-L-Leu-erythro-β-methyl-D-isoAsp-L-Ala-Adda-D-Glu-N-methyldehydroAla)(17a), where Adda refers to the novel
Structural studies on cyanoginosins-LR, -YR, -YA, and -YM, peptide toxins from Microcystis aeruginosa
The structures of the hepatotoxins of general name cyanoginosins-XY are proposed to be cyclo-D-Ala-L-X-erythro-β-methyl-D-isoAsp-L-Y-Adda-D-isoGlu-N-methyldehydroAla (1) where X and Y represent
Separation of Bitis gabonica (Gaboon adder) venom arginine esterases into kinin-releasing, clotting and fibrinolytic factors.
TLDR
Distinct biological properties were found for the esterases, E-I, EII and E-III showing kinin-releasing, fibrinolytic and clotting activity, respectively.
Bitis gabonica venom. The amino acid sequence of phospholipase A.
TLDR
Cyanogen bromide cleavage, and tryptic and chymotryptic digests provided the necessary overlapping peptides allowing the derivation of the complete amino acid sequence in Bitis gabonica phospholipase A.
A partial structure for the toxin BE-4 from the blue-green algae, Microcystis aeruginosa
The amino acid sequence of a peptide fragment of a peptide toxin isolated from the blue-green algae, Microcystis aeruginosa, is D-Ala-L Leu-erythro-β-methyl-D-isoAsp-L Ala-Baa-D-Glu, where Baa is a
Kaffircorn malting and brewing studies XVII—Purification and properties of sorghum malt α‐amylase
α-amylase of sorghum malt has been purified by a combination of charcoal and heat treatment, DEAE-cellulose and calcium phosphate chromatography, and gel filtration, yielding a product with a
A Neurotoxin, Toxin α, from Egyptian Cobra (Naja haje haje) Venom I. PURIFICATION, PROPERTIES, AND COMPLETE AMINO ACID SEQUENCE
Abstract A neurotoxin, designated toxin α, has been isolated from the venom of the Egyptian cobra (Naja haje haje) by gradient chromatography on Amberlite CG-50, and has been further purified by gel
