Ornibactin C6 1 mg

Siderophores

Pure C6 Ornibactin (3-hydroxyhexanoic acid as acyl group).

The ornibactins represent modified tetrapeptide siderophores, possessing the sequence L-Orn1(N-OH, N-acyl)-D-threo-Asp(-OH)-L-Ser-L-Orn4(N-OH, N-formyl)-1,4-diaminobutane. The N-acyl groups of Orn1(N-OH, N-acyl) may vary and represent the three acids 3-hydroxybutanoic acid, 3-hydroxyhexanoic acid and 3-hydroxyoctanoic acid, leading to a mixture of three different ornibactins, designated according to their acyl chain length as ornibactin-C4, ornibactin-C6 and ornibactin-C8.
