The molecule is an L-alpha-amino acid obtained by enzyme-mediated intramolecular cyclisation of L-arginine. It has a role as a metabolite. It is a member of guanidines, a member of pyrimidines, a L-arginine derivative and a non-proteinogenic L-alpha-amino acid. It is a conjugate base of a (2S,3R)-capreomycidine(1+).
