C3:G70 in the acceptor stem is crucial for accurate AUG selection and rapid TC binding to PICs in vivo. (A) Acceptor stem structures and phenotypes (in order of severity: Sui3− > Sui2− > Sui > Sui−/+) for 3:70 substitutions. (B) Slg phenotypes on +His medium analyzed as in Figure 1C. (C) His+/Sui phenotypes analyzed as in Figure 2B. (Results in B and C were obtained in parallel from the same plates and rearranged only for ease of interpretation.) (D) UUG:AUG initiation ratios were determined as in Figure 1B. (E) β-Galactosidase expressed from the GCN4-lacZ reporter on p180 measured as in Figure 1B.
