I think it depends how to you express the enzyme in the rate law,
consider the two examples below:

v = Vmax * S / (Km + S)

Is the Vmax a modifier or a parameter, I think I would consider it a
parameter in this case.

Or

V = E * kcat * S / (Km + S)

In this case the enzyme concentration is explicit and I would imagine in
this case that the E symbol could be treated as a modifier.

Subject: [sbml-discuss] A model representation in SBML in which the
enzyme represented as a Modifier

Hi All,
I am developing a tool to convert genesis (.g) files to SBML format. Can
some one direct me to a model representation in SBML in which the enzyme
is displayed under Reaction structure expressed as a Modifier. Most of
the examples on the SBML repository don't show enzyme as Modifiers.
