Various approaches for monocistronic constructions of genetic circuits have been designed for metabolite production but there has been no attempt to apply such methodology for aminoglycosides biosynthesis. Here, a simple and commercially available bio-part, despite the current trend focusing on the standardized BioBricks bio-parts available in the registry, is used. A 181-bp nucleotide fragment was designed for the efficient construction of an expression vector for monocistronic assembly of genes. Furthermore, a single vector with multi-monocistronic assembled genes for 2-deoxystreptamine (2-DOS) synthesis was constructed for production in engineered Escherichia coli. The working efficiency of model vector was concluded by reporter assay whereas the expressions of biosynthesis genes were confirmed by RT-PCR and SDS-PAGE. Production of 2-DOS was confirmed by TLC, LC-ELSD, and ESI-MS/MS.
