Structure of HC-toxin

Structure of HC-toxin, cyclo(D-Pro-L-Ala-D-Ala-Aeo), whereAeo stands for 2-amino-9,10-epoxi-8-oxodecanoic acid. The maize Hm1gene confers insensitivity to HC-toxin and hence resistance to C. carbonum. Hm1 encodes HC-toxin reductase, which detoxifies HC-toxin by reducing the 8-carbonyl group to an alcohol.
