Leader peptidase A (LepA) is an elongation factor that is thought to back-translocate on the ribosome during the translation of RNA to proteins in all prokaryotes and eukaryotes that have maintained functioning mitochondria. There are three primary elongation factors (EF-G, EF-Tu, EF-Ts) that are known to be the main contributors to facilitate elongation during protein synthesis; due to LepA's now acknowledged proofreading function in translation, scientists are now lobbying to have LepA renamed as EF-4 (elongation factor 4).
Famous quotes containing the word leader:
“A political leader must keep looking over his shoulder all the time to see if the boys are still there. If they arent still there, hes no longer a political leader.”
—Bernard Baruch (18701965)
