제목 Metabolic Engineering using Synthetic Small Regulatory RNA based Rapid Gene-Knockdown Technique for Enhanced Production of Cadaverine and Tyrosine
초록 Small regulatory RNAs (sRNAs) are gene regulators that act on post-transcriptional phase. Here, we developed synthetic a sRNA gene knockdown technique. Synthetic sRNA properly repressed DsRed2 and was used to enhance the production of tyrosine and cadaverine. Through screening of 14 different strains with sRNAs, we isolated a strain producing 2 g per liter of tyrosine and using a library of 130 synthetic sRNAs, murE was isolated and showed a 55% increase in cadaverine production.
