This is a control sRNA that targets a non-coding region in the genome of ''S.epidermidis'' (2314773-2314796) which is a intergenic region that is downstream of two genes on two different strands. It contains binding energy of only -7.8 kcal/mol to YFP gene as determined using DINAMelt software (http://mfold.rna.albany.edu/?q=DINAMelt/Two-state-melting). For effective binding, sRNA must have binding energy between -30 kcal/mol to -40 kcal/mol (Yoo et al., 2013). This shows that control sRNA cannot effectively bind YFP and it serves as a control which allows us to determine if production of sRNA places a metabolic load on the organism (Dokyun et al., 2013).

sRNA control for S. epidermidis: targets the non-coding region

Small RNAs (sRNAs) are small double-stranded transcripts capable of silencing mRNAs of complementary sequence (Yoo et al., 2013). The sRNA sequence was designed with two functional parts: a region complementary to the target mRNA (target binding site) and MicC scaffold region for recruitment of Hfq BBa_K1323004, a protein which enhances the hybridization between the sRNA and target mRNA (Yoo et al., 2013). The MicC RNA sequence is the best scaffold sequence as shown by previous studies done by the same research group (Na et al., 2013). This is a control sRNA that targets a non-coding region in the genome of S.epidermidis (2314773-2314796) which is a intergenic region that is downstream of two genes on two different strands.
