dc.description.abstract | High levels of 4-methyleneglutamine accumulate in the roots and leaves of Sophora japonica, but no detectable amounts of 4-methyleneglutamic acid and only trace quantities of 2-oxo-4-methyleneglutaric acid are seen. 4-Methylglutamic acid, however, is present in leaves and roots at a level 5-25% of that found for 4-methyleneglutamine; 2-oxo-4-methylglutaric acid is the most abundant keto acid detected in 28-day leaf extracts, but no 4-methylglutamine is seen. Transamination by pig heart glutamate: oxalacetate aminotransferase of the 2-oxo-4-methylglutaric acid that occurs in this species yields erythro-4-methylglutamic acid; the 2-oxo acid, therefore, has the (4R) configuration. The 4-methylglutamic acid isolated from this plant is also the erythro isomer and is probably of the (2S, 4R) configuration. This is the first report of the presence of 4-substituted glutamic acids in Sophora and the first instance where high levels of 4-methyleneglutamine are present in the absence of detectable levels of 4-methyleneglutamic acid. | en_US |
