I have been using the recombinant bovine enterokinase (from Invitrogen)
to cleave my fusion protein. Recognition sequence: (Asp)4-Lys
The system works almost perfectly, except that I get two proteins: mine
and mine with the first four AA deleted (Ala-Lys-Ser-Arg).
Have you ever heard of unspecific cleavage of this kind (i.e after any
basic residue) with enterokinase ???

thanks for help
alex
