2 questions:

• SimplifiedEnzymeConstrainedModel does not need the same treatment?
• do we want to enforce the "enzyme's mass" semantics for the whole enzyme semantics?

[stelmo]

So simplified enzyme does not have protein variables, so this is not needed there.
Not sure what you mean for the second question?
