Figure 6From: Active site plasticity revealed from the structure of the enterobacterial N-ribohydrolase RihA bound to a competitive inhibitorActive site versatility of RihA. Molecular surfaces at the RihA active sites of two independent molecules. Two orthogonal views are shown, highlighting the existence of empty cavities that may accommodate different types of substrates. Panels A) and B) depict the surfaces of chain A and chain D, respectively.Back to article page
