Marinobacter hydrocarbonoclasticus petrobactin

Siderophores isolated from marine microorganisms contain iron-binding moieties similar to their terrestrial counterparts catecholates, hydroxamates, and a-hydroxycarboxylates. Isolated hydroxamates include Ferrioxamine from Vibrio strain BLI-4, the aquachelins " from Halo-monas aquamaria, and the marinobactins " from Marinobacter species DS40M6 and DS40M8. Petrobactin from Marinobacter hydrocarbonoclasticus includes both catecholate and citrate... [Pg.145]

Transition-metal complexes of a-hydroxy acids can be photolabile. The oil-degrading marine bacterium Marinobacter hydrocarbonoclasticus produces a siderophore, which appears to exploit photodecarboxylation to facilitate iron release. Petrobactin (Figure 4) forms a stable ferric complex through iron chelation by two catecholate moieties and a citryl group. Decarboxylation of the citryl moiety via photolysis of ferric petrobactin yields a less stable ferric complex than the... [Pg.154]
