The anthranilate synthetase activity of the enzyme complex was quite unstable unless glutamine, MgCl2, TRIS and, most importantly, glycerol were included in the extraction buffer. The three-enzyme complex showed a molecular weight of 400,000 when estimated using Sephadex gel filtration, and a molecular weight of 200,000 when using sucrose density gradient centrifugation. At least two bands of anthranilate synthetase were detected on disc gel electrophoresis. An enzyme complex containing phosphoribosyl anthranilate synthetase and indoleglycerol phosphate synthetase, but no anthranilate synthetase, was isolated from Claviceps. This enzyme complex had an apparent molecular weight of 165,000 as estimated by sucrose gradient centrifugation. Anthranilate synthetase is inhibited by L-tryptophan and elymoclavine, the terminal ergot alkaloid produced by this strain of Claviceps.

The analytical procedure consisted of extracting the toxins from dried mushroom tissue, defatting, fractionating the toxins by adsorption chromatography on Sephadex LH-20, desalting and running thin-layer chromatograms of appropriate fractions along with authentic toxin samples. One amatoxin, amanin, was identified by hydrolysis to its components amino acids. Except for some difference in relative amounts of toxins, American and European varieties of A. phalloides were quite similar. Neither phallotoxins nor amatoxins were present in three out of four collections of A. verna; the fourth contained only a trace of beta-amanitin. Amanin was the sole of amatoxin present in two out of four collections of A. virosa; alpha-amanitin was the chief amatoxin in the other two. None of the white Amanita species contained phallacidin.
