Usage and Biology

SP126(BBa_K3889010), SP146(BBa_K3889011) and SP200(BBa_K3889012) are a part of synthetic library promoters from Liu et al. (2018)[1]. These synthetic promoters are characterised to have constitutive expression, hence they can be used in general protein production. The library contains 214 synthetic promoters providing variability and robustness in expression, according to the system's need. All SP promoters have the following consensus sequences:

Modelling

We planned to use SP126 with BBa_K1351033 for gene expression of SRTF1 (BBa_K3889100).
