50S
Izvor: Wikipedija
50S je veća podjedinica 70S ribozoma prokariota. Ona sadrži mesto inhibicije za antibiotike poput makrolida, hloramfenikola, klindamicina, i pleuromutilina. Ovaj kompleks sadrži 5S ribozomnu RNK i 23S ribozomnu RNK.
50S, koja je ekvivalentna sa 60S ribozomalnom podjedinicom eukariotskih ćelija, je velika podjedinica 70S ribozoma prokariota. 50S podjedinica se prvenstveno sastoji od proteina ali isto tako sadrži i jednolančanu RNK poznatu kao ribozomna RNK (rRNK). rRNK formira sekundarne i tercijarne strukture kojima se održava aktivna struktura ribozoma.
