  • a MSMEG_2148 is 544 amino acids. Ser534 frameshift hypothetically replaces the 8 C-terminal amino acids with a different 23-amino-acid sequence.

  • b MSMEG_0639 is 336 amino acids. Lys12 frameshift hypothetically replaces the 325 C-terminal amino acids with a different 24-amino-acid sequence.

  • c MSMEG_5061 is 465 amino acids. Glu225 frameshift hypothetically replaces the 241 C-terminal acids with a different 236-amino acid-sequence.

  • d Bold text indicates the genes that were mutated in WT to test for aggregation defects.

  • e His-Asn-His (HNH).
