From @txellext
I am not sure we can use catalyst definition as it is for a cell biocatalyst. We should specify that the strain is engineered to increase the rate of a reaction and this is not always true: e.g. if the strain chassis by its nature doesn't have the genes at all you do not increase the rate, you make it happen where the reaction would not take place at all...
