CDS_Lv0_BOH_2_A

This composite part corresponds to a phytobrick compatible MoClo Lv.0 CDS element. This part is an artificial operon designed to express the enzymes CDS_NphT7 (BBa_K3726000), CDS_PhaB^173S (BBa_K3726001), CDS_Ccr (BBa_K3726002), CDS_PhaJ (BBa_K3726003), CDS_PduP (BBa_K3726004), CDS_Slr1192 (BBa_K3726005).

Within this artificial operon each CDS element is preceded by an in-silico designed RBS sequence using DeNovo DNA software. Only the first coding sequence of the operon is not preceded by an RBS sequence which must be assembled during the level 1 MoClo reaction for the expression of the operon in a level 1 transcriptional unit.

This part has been used within the iGEM MADRID_UCM 2021 iGEM team for the expression of a butanol biosynthesis pathway.

In particular, this polycistronic level 0 part codifies for the CDS_NphT7, CDS_PhaB^173S, CDS_Ccr and CDS_PhaJ enzymes of the pathway.

The relative transcription initiation strengths of each RBS in the operon context has been calculated with DeNovo DNA Software. Results are depicted in the graphic below.

Internal RBS sequences are conserved from BOH3 part (BBa_K3726011). Transcription initiation rate is high for the encoded enzymes.
