6-L-alanineferrirubin, a ferrichrome-type siderophore from the fungus Aspergillus ochraceous.
The molecular structure of 6-L-alanineferrirubin tetradecahydrate, [Fe(C41H64N9O16)].14H2O, has been determined in order to confirm its chemical structure. The structural results show that the presence of an alanine in place of a serine or a glycine at position 6 in the cyclic hexapeptide has very little effect on the conformation of the 18-membered ring or on the geometry of the octahedral iron coordination.
