Specific interactions of E site binding. (A) The E site ligands interact with both rRNA (gray) and L44e (green). (B) A76 stacks in between 23S rRNA nucleotides G2459 (2421) and A2460 (2422), and hydrogen bonds with universally conserved C2431 (2394). (C) C75 interacts with L44e through hydrogen bonding to Gly 57 and Arg 40, and hydrophobic packing with Lys 54, Lys 51, and Phe 52.
