Query on LYSIS proteolysis database for PC

[Mr. P.A. Sansom]

Does anybody have experience of the LYSIS proteolysis database for PC, 
available from Springer-Verlag? We are thinking of purchasing it, but want
to know if it is ever updated, and if it will indicate cleavages in a sequence
that we define. 
Thanks in advaance for your help.
