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) in our ribozyme-assisted polycistronic co-expression system：pRAP. The RNA sequence of ribozyme before the cds can conduct self-cleaving in mRNA, and the polycistronic mRNA transcript is thus co-transcriptionally converted into individual mono-cistrons in vivo.Self-interaction of the polycistron can be avoid and each cistron can initiate translation with comparable efficiency.[1] To protect the mono-cistron mRNA from degradation, a stem-loop structure is placed at the 3' end of the CDSs.[2]
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.
