a
Based on AlphaFold predictions of ancestral protein structures.
b
Based on analyses of extant sequences. Values greater than 30 are bold-faced. See Supplementary File 8 for details.
c
0% in 1A, 75% in 1B.
d
Because Group 7 is paraphyletic, we could not confidently infer the conservation of PB domains based on AngGroup6/7.
