The overall structure of CbpD. (a) The structure of CbpD contains an AA10 domain (green) with an L2 region (slate) between β1 and β2 connected to a GbpA2 domain (yellow) by flexible linker regions (gray). Disulfide bridges and the active-site His residues are shown as sticks. (b) The structure-based topology diagram for CbpD was initially generated with Pro-origami (Stivala et al., 2011), and the long intervening stretches were shortened manually and are not to scale. (c) A comparison of the AA10 and GbpA domains from the CbpD structure and predicted structural domain models from RoseTTAFold (Baek et al., 2021; pink) reveals a high degree of predictive accuracy. The all-atom r.m.s.d.s between the predicted and crystallographic AA10 and GbpA2 domains are 1.5 and 1.6 Å, respectively. |
