  1. Alignments performed using the BLASTp suite. Highlighted are the putative functions and respective domain IDs as identified by InterPro (when available), HHPred analysis (> 90% probability; PDB IDs provided), and in-house AlphaFold modeling analysis. Brackets provide overall protein length and AA residues for each alignment. n.s.s. no significant similarity found. Complementary sequence alignment using tBLASTx is provided in Table S3. Source data are provided as a Source Data File.
