Collection of regulogs for L20_leader (RF00558) RNA regulatory element

The ribosomal L20 leader is an RNA regulatory element that was found upstream of the Bacillus subtilis operon infC-rpmI-rplT encoding translation factor IF3 and the ribosomal proteins L35 and L20. The expression of this operon is autoregulated by a complex transcription attenuation mechanism involving the formation of alternative structures in the leader mRNA which depends upon the presence of ribosomal protein L20 [17289755]. L20 binds to a phylogenetically conserved domain and provokes premature transcription termination at the leader terminator. A regulatory model for L20 leader is based on molecular mimicry between the L20-binding sites on ribosomal and messenger RNA [17289755]. more
