N Clone of Mammal Ribozyme
The N Clone of Mammal Ribozyme is a riboswitch that cleaves itself in the presence of theophylline. It has a five nucleotide (nt) base change from the Mammal Ribozyme (J119446). At nt 77-81, the original ribozyme sequence of CATAA was edited to AATAA. It is cloned into the pSB1A2-BR vector, allowing for gene expression using a T7 promoter. The sequence for the original Mammal Ribozyme is found in Massively Parallel RNA Device Engineering in Mammalian Cells with RNA-Seq (https://www.nature.com/articles/s41467-019-12334-y).

Charcterization and improvement in 2021 by SJTU-BioX-Shanghai
In 2021, SJTU-BioX-Shanghai improved the sensibility of this part, see BBa_K3714004 for more details. In short, we improved the performance (cleave fraction) with theophylline present in vitro by introducing some mutation in the loops of aptazyme.
