Enzymatic Product release question

[William P. Tschantz]

Hi

I am looking for examples of any proteins that the product does not 
dissociate from the enzyme till either new substrate binds or someother 
protein accepts the product from the enzyme.

I am not aware of anything out in the literature, but then i do not know 
what type of search words to use in a literature search of the above 
topic.  Any help greatly apprecieated.

Thanks in advance

Bill
