Figure 2
Structure of the two-domain construct 46E–47I from the M. mulieris adhesin and its comparison with the Cpe0147 and Spy0128 proteins. (a) M. mulieris adhesin domains (ester domain in blue; isopeptide domain in green) overlaid with Cpe0147 domain 2 (PDB entry 4ni6; yellow) and Spy0128 adhesin domain 2 (PDB entry 3b2m; yellow). (b) Topology diagram of the M. mulieris adhesin domains. The N-terminal ester domain is coloured blue with the cross-link shown as a bold horizontal line joining the first and last strands of the domain. The C-terminal isopeptide domain is coloured green with cross-links shown as bold horizontal lines. The isopeptide bond links strands 1 and 9, while the disulfide bond links strands 2 and 5. Each domain topology is similar to either the Cpe0147 or Spy0128 proteins but with four major changes as indicated in (a). |
