a) Gene names used in the published genome of AMB-1 [8]. A new ORF we identified is temporarily referred to as NEW_GENE. b–c) Position of putative initiation codon on the bacterial chromosome. *, annotated initiation codon changed adding 18 residues to the gene product. **, annotated initiation codon changed adding 206 residues to the gene product. The entire MamE-like sequence is given in Figure S1. c) Position of stop codon on the bacterial chromosome. d) Homologous proteins encoded within the magnetosome island. e–f) Percentage of identity and similarity (BLOSSUM62 matrix) between putative proteins encoded by genes listed in a) and Mam proteins listed in d). g) Gene names used hereafter.
