Log odds ratios for each codon with at least one synonym for the 6 E. coli specific features.

VedIO: 5’ enrichment in the experimental transgene data (top 25% by Prot. FCC v bottom 25%); V5-core: enrichment in the 5’ end of all E. coli native genes versus the core. V5-prot: 5’ enrichment in the native gene data (top 25% by protein abundance v bottom 25%); VTO: core CDS enrichment in the native gene data (top 25% by protein abundance v bottom 25%); Vnoise: 5’ enrichment in the low noise native gene data (bottom 25% by noise v top 25%); Vess: 5’ enrichment in essential genes (essential v non-essentials).
