Extended Data Fig. 1: Conservation of SpeFL across γ-proteobacteria.
From: Ornithine capture by a translating ribosome controls bacterial polyamine synthesis
a, Phylogenetic tree showing the distribution of representative speFL sequences from several orders of γ-proteobacteria. b, Multiple sequence alignment of SpeFL homologs from different species. The sequence shown for Salmonella Typhimurium corresponds to the previously reported orf347. SpeFL and its homologs belong to the group of proteins of unknown function DUF261854. The stop codon found after each sequence is indicated on the right of the alignment.
