Extended Data Fig. 5:

B. subtilis Rho is more selective than E. coli Rho. Related to Fig. 2. a, As in Fig. 2b, but overlaid with sequences strongly terminated by E. coli Rho in vitro (orange X)³⁴. b, Distribution of Rho target scores for E. coli Rho-terminated sequences shown in a. Dashed line indicates enrichment cutoff of 1.
