Rampant Exchange of the Structure and Function of Extramembrane Domains between Membrane and Water Soluble Proteins
(A) Conserved catalytic sites between structurally aligned membrane and soluble protein domains. (B) Alignment of envelope structure-factor and phophotyrosyl phosphase. Catalytic sites are depicted on the structural alignment. (C) Alignment of penicillin-binding protein and OXA-10 beta-lactamase.
