The novel amino acid 2,4-diamno-3-methylbutanoic acid has been identified in nodules formed by two strains of Rhizobium bacteria on Lotus tenuis roots.Retention time measurements on a Chirasil-Val capillary column suggest it is present as the (2R,3S)-enantiomer.Several isomeric diamino acids were synthesized for comparative studies.
