conversion of rate to kcat?

Hi! Thanks for your answer.

I want to express the enzymatic rate (or V) as kcat at different points
during a reactions.

For example: The concentration of the enzyme is 1.5mg/ml and the
activity is 72 nmol/min at 5 mintues into the reaction. Then what is
the kcat at that point of the reaction.

Is this possible? Or do i need a vmax value to work around?

/Regards, Joakim
