A Conserved Proline Triplet in Val-tRNA Synthetase and the Origin of Elongation Factor P
Bacterial ribosomes stall on polyproline stretches and require the elongation factor P (EF-P) to relieve the arrest. Yet it remains unclear why evolution has favored the development of EF-P rather than selecting against the occurrence of polyproline stretches in proteins. We have discovered that onl...
