Part:BBa_K5115038
ribozyme connected: MTA, Hpn, RcnR_C35L

Introduction
This composite part combines BBa_K5115035(ribozyme+RBS+MTA+stem-loop), BBa_K5115036(ribozyme+RBS+hpn+stem-loop)and BBa_K5115033(ribozyme+RBS+RcnR_C35L+stem-loop) . We introduced this ribozyme-assisted polycistronic co-expression system in 2022. By inserting ribozyme sequences between CDSs in a polycistron, the RNA sequences of Twister ribozyme conduct self-cleaving, and the polycistronic mRNA transcript is thus co-transcriptionally converted into individual mono-cistrons in vivo.
With this design, we achieve co-expression of MTA, hpn, RcnR C35L at similar level. MTA is a protein that can bind with nickel ions to reduce its toxity to the E.coli. The Hpn is a protein that can sequester metals that accumulate internally to reduce nickel's toxity to the E.coli. RcnR C35L can regulate the nickel ion channel proteins in the cell membrane to tune the nickel ion transport rate.
