Protein Structure from Scientific Research

Close-ups of the CarHTt binding site pocket with Ado of bound AdoCbl or AdoRhbl. Protein backbone: lime green; C atoms of binding residues in yellow, of corrin ring in magenta and upper axial Ado in orange; Co(III)-center: blue ball; Rh(III)-center: grey ball. Major calculated structures for CarHTt-bound AdoRhbl sampled near=320° and=207°
