NB Although the relative configuration of the epoxide moiety has been assigned as trans, it has not yet been established whether the absolute configuration is R,R (as drawn) or S,S. It has a role as a bacterial metabolite. It is a tautomer of a 3-amino-N-(trans-3-carbamoyloxirane-2-carbonyl)-L-alanine."}]
