Structural characterization of core-bradavidin in complex with biotin
Fig 1
Superimposition of the Cα traces of subunit I of core-bradavidin (orange) [PDB:4BBO], wt bradavidin (magenta) [PDB:2Y32] and chicken Avd (cyan) [PDB:1AVD].
For clarity, only the biotin bound to core-bradavidin is shown (stick model). The loop regions L1,2 to L7,8, and the N and C termini, are labelled.
