The codon usage frequency of the six rarest codons in antibiotic gene clusters of P. protegens Pf-5. The codon usage frequency refers to the number of times a specified codon was identified per 1000 codons in the annotated coding sequences of Pf-5 (black bar) or within a specific gene cluster (colored markers).
