Chemistry of marine ligands and siderophores
WebWe have already encountered the low molecular weight iron binding siderophores in Chapter 4, Biological Ligands for Metal Ions, and we will describe the way in which they are taken up by bacteria below. Two structural features dominate the majority of the marine siderophores which have been identified and characterized from marine bacteria. WebSep 20, 2011 · A large proportion of these ligands have also been shown to be similar in size (300–1000 Da) and to contain iron-binding functional groups similar to siderophores (Macrellis et al., 2001). It has thus been suggested that a considerable part of strong Fe-binding ligands in the ocean are in fact siderophores (Macrellis et al., 2001).

WebThis dissertation investigates siderophore production of a group of marine bacteria belonging to the Marinobacter genus, some of which were isolated from lab cultures of dinoflagellates and coccolithophores, in response to iron limitation. Iron is arguably the most important micronutrient in the marine environment due to its involvement in many vital … WebSiderophores (Greek for “iron carrier”) are low-molecular-weight, high-affinity iron-chelating compounds that are produced by organisms to solubilize Fe3+ for uptake. They are produced by aerobic and facultative microorganisms in oxic environments to scavenge iron from insoluble iron minerals.
WebThe known siderophore vibrioferrin has been isolated from species of Marinobacter required for the growth of the toxic, bloom forming dinoflagellate Gymnodinium catenatum. A number of unique attributes of this siderophore, including its ability to bind boron, may provide important clues as to the nature of this and related algal-bacterial relationships.
