Figure 2. Key differences in CI accessory subunits between V. radiata and opisthokonts.

Accessory subunits NDUS6 and NDUA12, NDUA8 and NDUC2 of V. radiata (this study), Y. lipolytica (PDB:6RFR) and O. aries (PDB: 6QA9) are shown as surface for comparison. (A) NDUS6 (green) and NDUA12 (orange), with an additional label for NDUA9. (B) NDUA8 (maroon), with additional label for the V. radiata’s carbonic anhydrase domain (CA). (C) NDUC2 (blue), with additional label for the V. radiata’s CA.
