FIG. 5.
Similarity of NlmA and NlmB with other peptides in GenBank. (A) Sequence alignment of NlmA and ThmA; (B) sequence alignment of NlmB and LafA. ThmA and LafA are each one of two components in the two-peptide nonlantibiotic bacteriocin thermophilin 13 and lactacin F, respectively. Dark gray boxes represent identical amino acids; light gray boxes denote conserved changes; arrows indicate cleavage sites for the prepeptide.
