Synthetic Promoters data from SP1-214[1]

Usage and Biology

SP126(BBa_K3889010), SP146(BBa_K3889011), SP200(BBa_K3889010) 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. Since 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:

Based on this the promoters are as follows:

Modelling

We planned to use SP146 with BBa_K1351030 for gene expression of mf-Lon (BBa_K3889122).

Parameters used:

Rate of mf-Lon production =5.7885 ⁷ nM/day

Rate of mf-Lon degradation = 1.69/day
