Parameters
The parameter of this reaction is the degradation rate of R (
). The parameter values were derived from proteomics studies on different proteins of S. coelicolor.

Parameters with uncertainty
The most plausible parameter value for the is decided to be 
and the confidence interval 
. This means that the mode of the PDF is 0.00118 and the range where 95% of the values are found is between 
and 
.
The probability distribution for the parameter, adjusted accordingly in order to reflect the above values, is the following:
The location and scale parameters of the distribution are:
