原始语种摘要: Abstract(#br)Different mRNA stabilizing elements including the 3′-stem-loop, the ribosome binding sites (RBS), the 5′-stem-loop and the spacer region between the RBS and the 5′-stem-loop were analysed in detail to increase mRNA stability resulting in enhanced expression of heterologous proteins. In addition, in combination with mRNA stabilizing elements, we propose a new class of 5′-mRNA controllable stabilizing element (CoSE) which is composed of a transcriptional operator such as lacO of the Escherichia coli lac operon and a suitable RBS followed by an optimal spacer length. Such a CoSE allowed Bacillus subtilis cells to synthesize extraordinary stable transcripts with a half-life of the model bgaB reporter transcript (codes for an β-galactosidase gene derived from Bacillus...
