'''AZOTOBACTER VINELANDII PERIPLASMIC MOLYBDATE-BINDING PROTEIN'''<br />


==Overview==
==AZOTOBACTER VINELANDII PERIPLASMIC MOLYBDATE-BINDING PROTEIN==
Background:. Periplasmic receptors constitute a diverse class of binding, proteins that differ widely in size, sequence and ligand specificity., Nevertheless, almost all of them display a common beta/alpha folding motif, and have similar tertiary structures consisting of two globular domains., The ligand is bound at the bottom of a deep cleft, which lies at the, interface between these two domains. The oxyanion-binding proteins are, notable in that they can discriminate between very similar ligands., Results:. Azotobacter vinelandii is unusual in that it possesses two, periplasmic molybdate-binding proteins. The crystal structure of one of, these with bound ligand has been determined at 1.2 A resolution. It, superficially resembles the structure of sulphate-binding protein (SBP), from ... [[http://ispc.weizmann.ac.il/pmbin/getpm?9862806 (full description)]]
