Figure 1: The ϕ11 RBP overall structure and domains.
From: Structure of the host-recognition device of Staphylococcus aureus phage ϕ11
(A) The structure of the complete RBP trimer is represented as a ribbon, with monomers coloured blue, green and violet. (B) The trimeric N-terminus of the ϕ11 RBP has been superposed onto the 30 first amino acids of the trimeric TP901-1 RBP (r.m.s.d. of 1.8 Å). (C) Schematic representation of the Fe3+ binding motif. (D) The 5-bladed propeller domain rainbow coloured from dark blue (N-terminus) to red (C-terminus). The components of blade 5 are the N-terminal and C-terminal β-strands of the domain. (E) The two C-terminal trimeric domains, each assembling into three 4-stranded β-sheets. (F) Superposition of the two C-terminal domains. The r.m.s.d. between these domains after superimposition is 1.7 Å (blue and red structures).
