Corynebactin

3,7,11-Tris[2-(2,3-dihydroxybenzoylamino)acetylamino]-4,8,12-trimethyl-1,5,9-trioxacyclododecane-2,6,10-trione

C39H42N6O18 (882.2555472000001)


A crown compound that is enterobactin in which the pro-R hydrogens at positions 2, 6 and 10 of the trilactone backbone are replaced by methyl groups, and in which a glycine spacer separates the trilactone backbone from each of the catecholamide arms. It is the endogenous siderophore of Bacillus subtilis, used for the acquisition of iron.
