Part:BBa_K844013
tRNA expression cassette for spider silk "B" proteins
The tRNA sequences for use in overexpression of spider silk proteins were selected from the Genomic tRNA Database for E. coli K-12. tRNA sequences with anti-codons recognizing the codons used in the optimized “B” and “F” subunits were selected, and their native sequences used. The part with six tRNAs (BBa K844012) corresponding to the codons used in the “F” construct were made into a single construct with each gene proceeded by the ZH14 12x tRNA promoter and followed by the downstream region of the E.coli Ala (GCC) sequence. This five tRNA construct (BBa K844013) contains additional tRNAs for the glycine, proline, and serine amino acids, as well as two additional tRNAs that have anticodons matching the threonine and arginine amino acids that is generated in the scar sites from use of the BioBrick Assembly Standard #23 cloning method. Note: All tRNAs are from E. coli K12 except the Arg(TCT) tRNA is from Escherichia_coli_O157H7 since the K12 ARG tRNA had an internal PstI site.
