↵a Sequential ROEs were observed between H-1 of moiety A and H-2 of moiety B and between H-1 of moiety B and H-3 of moiety C.

↵b The moieties of the exotoxin, Rha-Rha-C

_{14}-C_{14}, are as follows: A, the first rhamnose; B, the second rhamnose; C, the first C_{14}sequence; and D, the second C_{14}sequence.↵c All methylene group signals form C

_{5}to C_{13}.
