From: Transcription of the extended hyp-operon in Nostocsp. strain PCC 7120
The secondary structures formed by the repeated conserved sequences (cs) R2, R3.1, R4 and R5 found within the intergenic regions of the extended hyp -operon. Predicted ΔG melting energies are shown for each putative hairpin structure. Conserved sequence R5 (csR5) is identical to the previously described LTRR in Nostoc sp. strain PCC 7120 [24].
