Part:BBa_K4011017

pRPL8B-AeAT9-tSSA1

pRPL8B-AeAT9-tSSA1 is an expression cassette in S. cerevisiae capable of expressing AeAT9, which will synthesize ethyl-acetate from acetyl-CoA and ethanol. This is the second step into our pathway to turn acetate and ethanol into ethyl-acetate. pRPL8B BBa_K4011020, AeAT9 BBa_K4011006, and tSSA1 BBa_K4012020 were used to construct pRPL8B-AeAT9-tSSA1 using Golden Gate assembly. This part was used to construct pTEF1-SaACS2-tADH1-pRPL8B-AeAT9-tSSA1 BBa_K4011018.

Usage and Biology

AeAT9 is an alcohol acyltransferase from Actinidia eriantha, otherwise known as kiwifruit. Its general function is to convert alcohols into esters. The fruity smell one smells from kiwifruit it largely a result of AeAT9. pRPL8B is a medium strength promoter and tADH1 is a relatively strong terminator both characterized by Lee et al in 2021.

Source

pRPL8B and tSSA1 all come from S. cerevisiae, while AeAT9 comes from Actinidia eriantha.

Design Considerations

1. All codons were optimized for S. cerevisiae based on S. cerevisiae codon bias.

2. BsaI restriction sites were added to the three basic parts used to construct pRPL8B-AeAT9-tSSA1 for Golden Gate assembly.

3. BsmB1 sites flank the composite part for further Golden Gate assembly construction.
