User:Inarus2/L15 leader inarus

The E. coli ribosomal S15 leader is an RNA element that can form two alternative structures found in the ribosomal S15 protein. One of the two alternate structures is a series of three hairpins, the other includes a pseudoknot. This structure causes translational regulation of the S15 protein. Only the final two hairpins are conserved in other species.
