Fig. 1. Schematic representations displaying the alignment of identified fusion (A, B, D & E) or fission (C) proteins in green microalgal species (A and D) and diatoms (D and E) with their
respective split or composite proteins. The amino acid positions that correspond to the beginning and the end of the alignment are indicated, as well astheboundariesoftheconserved
domains relative to the full-length protein. Asterisks beside the microalgal species names below denote that the particular species was chosen as a representative amongst others for the
purpose of the alignment comparison. A: Alignment of fusion protein alpha 1,2 mannosidase/Fra10Ac1 in the green alga V. carteri with the respective split proteins in the green alga
C. reinhardtii*. B: Alignment of fusion protein DOT1/riboflavin synthase in the green alga V. carteri with the respective split proteins in the green alga C. reinhardtii*. C: Alignment of fission
proteins COX2A and COX2B in the green alga V. carteri* with the respective composite protein in the red alga C. merolae. D: Alignment of fusion protein G6PDH/6PGDH in the diatom
P. tricornutum with the respective split proteins in the diatom T. pseudonana*. E: Alignment of fusion protein TIM/GAPDH in the diatom Phaeodactylum tricornutum* with the respective
split proteins in the red alga C. merolae.
