Phenazines.—Results on the biosynthesis of microbial phenazines from shikimic acid (previously published in preliminary form cf. Vol. 5, p. 44 and Vol. 7, p. 27) are now available in full papers.53 Additional results are that 2,3-dihydro-3-hydroxyanthranilic acid (140) was not a precursor for iodinin (141), nor was... [Pg.24]

Some compounds can arise from different sources in different organisms. 2,5-Dihydro-xybenzoic acid comes from shikimic acid (Chapter 50) in Primula acaulis but from acetate in Penicillium species. Outline details. [Pg.488]

Phenazines.—Consideration of structural relationships between the various microbial phenazines, in association with evidence on the way in which these metabolites are formed from two molecules of shikimic acid (151), leads to phenazine-l,6-dicarboxylic acid (152) as a likely common intermediate (Scheme 8), but it has not been found to act as a precursor for various phenazines, exemplified by phenazine-1-carboxylic acid (153). Although the dimethyl ester of (152) has been reported to be a precursor for (153) in Pseudomonas aureo-faciens, it could not be confirmed as such under various conditions. The dihydro-derivative (156) was likewise found not to be a precursor for (153) and (154) in P. aureofaciens. ... [Pg.28]

Incorporation experiments proved that lunularin (595) and lunularic acid (598) were biosynthesized by the shikimate-malonate pathway 288, 290). The co-occurrence of (595) and (598), and the presence of a lunularic acid decarboxylase in Lunularia cruciata and Conocephalum conicum indicated that a decarboxylation step was involved in forming naturally occurring C-14 stilbenes and their dihydro products 290, 292). [Pg.147]
