What Is A Siderophore?
Siderophores (Greek: "iron carrier") are small, high-affinity iron-chelating compounds that are secreted by microorganisms such as bacteria and fungi. They help the organism accumulate iron. Although a widening range of siderophore functions is now being appreciated. Siderophores are among the stron
Delftia acidovorans
Delftia acidovorans is a Gram-negative, motile, non-sporulating, rod-shaped bacterium known for its ability to biomineralize gold and bioremediation characteristics.
Cupriavidus metallidurans
C. metallidurans plays a vital role, together with Delftia acidovorans, in the formation of gold nuggets. It precipitates metallic gold from a solution of gold(III) chloride, a compound highly toxic to most other microorganisms.
Tryptophan tryptophylquinone (TTQ) formation
Tryptophan tryptophylquinone (TTQ) is an enzyme cofactor, generated by posttranslational modification of amino acids within the protein. Methylamine dehydrogenase (MADH), an amine dehydrogenase, requires TTQ for its catalytic function. From Wikipedia wher
Structural motif
In a chain-like biological molecule, such as a protein or nucleic acid, a structural motif is a common three-dimensional structure that appears in a variety of different, evolutionarily unrelated molecules. Johansson, M.U. (23 July 2012). “Defining and searching for structural motif
