Bacillus Subtilis Synthetic Promoter 126

This is a synthetically derived promoter sequence for the expression of genes in Bacillus subtilis.

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 used SP126 with BBa_K1351033 for gene expression of SRTF1 (BBa_K3889100).

Parameters used:

Rate of SRTF1 production = 3.2246 x 10³/day

Rate of SRTF 1degradation = 1.69/day
