An isotopic study of the conversion of anthranilic acid to indole.
Anthranilic acid and indole have been implicated as intermediates in the biosynthesis of tryptophan in several microorganisms (l-5). A mechanism of tryptophan synthesis from indole has been established, namely the pyridoxal phosphate-dependent coupling of indole and L-serine (6-9). Previous studies of the conversion of anthranilic acid to the indole ring of tryptophan have shown that the amino ...
متن کاملEnzymatic Formation of Catechol from Anthranilic Acid.
Anthranilic acid is known to be formed from kynurenine in animals and microorganisms (3-6) and to be degraded by cell-free extracts of a Pseudomonas species adapted to L-tryptophan (7). Catechol has been postulated as an intermediate in the catabolism of anthranilic acid on the basis of experiments utilizing sequential enzyme induction (8). Several groups of investigators have recently succeede...
متن کاملEnzymatic Conversion of Indole Acetaldehyde and Naphthalene Acetaldehyde to Auxins.
A neutral substance, convertible to an acid auxin, is present in various plant extracts (5, 9) and chemical preparations (9). As indicated by a number of biological tests, the neutral substance is in all likelihood 3-indole acetaldehyde and will for convenience be designated by this name in the present paper. In a previous paper (11) it was shown that 3-indole acetaldehyde is rapidly converted ...
متن کاملThe enzymatic conversion of homogentisic acid to 4-fumarylacetoacetic acid.
Although the probability that homogentisic acid is an intermediate in the conversion of phenylalanine and tyrosine to acetoacetate is indicated by many experiments with humans (l-5), animals (6-9), and tissue preparations (lO-13), no direct evidence has been reported concerning the mechanism of its oxidation. However, the formation of /?-ketoadipic acid from phenol in the presence of cholera Vi...
متن کاملThe enzymatic conversion of 5-dehydroshikimic acid to protocatechuic acid.
Previous studies of the physiology of an aromatic-deficient mutant strain of Neurospora crassa, Y7655a (1, 2), have led to the following conclusions: (a) The biosynthesis of the aromatic rings of phenylalanine, tyrosine, tryptophan and p-aminobenzoic acid proceeds in Neurospora as it does in Escherichia coli (3) via 5-dehydroshikimic acid and shikimic acid. (b) Protocatechuic acid, the major co...
