MetaCyc Compound: L-isowillardiine

Synonyms: 3-(uracil-3-yl)-L-alanine, β-uracil-3-ylalanine

Superclasses: an acid all carboxy acids a carboxylate an amino acid a modified amino acid
an amino acid or its derivative an amino acid a modified amino acid

Summary:
Willardiine is a non-protein amino acid naturally found in Acacia willardiana, Mimosa asperata, and pea (Pisum sativum). It exists as either a free amino acid, a γ-glutamylpeptide or a tripeptide. Isowillardiine, a willardiine isoform, is only detectable from the genus Pisum.

Chemical Formula: C7H9N3O4

Molecular Weight: 199.17 Daltons
