sfGFP + ASV tag
The superfolder green fluorescent protein (sfGFP) is a variant of the common green fluorescent protein, that folds faster, thus generating fluorescent in less time.
In order to quantify how the ASV tag affected the degradation rate of the sfGFP, a simple mathematical model was developed. The following model is exactly the same for the two scenarios, and consists of a constitutive expression minus a degradation rate (Equation.1). As both systems are constitutively regulated by the same promoter, the PJ23100 (BBa_J23100), the production rate will be the same in the two systems. In addition, the equations representing the steady-state (dy/dx=0) of the system were calculated (Equation.2).
With the Steady-State equations we are able to look for the relationship between the two degradation rates (δ) as the production rate is the same(Equation.3).
