Enzymatic conversion of formylaspartic acid to aspartic acid.
In previous investigations imidazoleacetic acid was shown to be quantitatively converted to formylaspartic acid by a partially purified enzyme preparation obtained from Pseudomonas sp. that requires DPNH’ and oxygen (2, 3). An intermediate in this process was isolated from the incubation mixture with highly purified enzyme preparations and was characterized as N-formimino-L-aspartic acid (4). E...
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...
متن کاملEnzymatic conversion of 3-hydroxyanthranilic acid to nicotinic acid.
The apparent conversion of tryptophan to nicotinic acid has been observed for several animal species (cf. (1)). Other studies demonstrated that at least some of the nicotinic acid (or amide) was synthesized within the tissues of the animal (2, 3). It was of interest to extend these studies and the ability of liver slices to synthesize nicotinic acid from its biologically active intermediate, 3-...
متن کاملConversion of acetate and pyruvate to aspartic acid in yeast.
Recent investigations by Ehrensviird et al. (1) have revealed that the carbon skeleton of aspartic acid in Torula yeast can arise readily from administered acetate. With C1aH&“OOH, the aspartic acid formed during growth contained Cl4 equally distributed between the two carboxyl groups, and most of the C** equally distributed between the 2 central carbon atoms. In the preceding papers (2, 3) the...
