Peptide mapping and Endo LYS-C: odd cut sites

Has anyone experienced Wako endo LYS-C cutting at amino acid residues other
than Lysine (K)? I have a client who is perplexed by my results and swears
there is a Lysine in the position I called a Leucine ( I stand by my
call). The endo LYS-C generated peptide sequence is as follows
(K) IGSQYDNYATC*L*AEHSLTEDDIFSIG...

Any experiences with this would be helpful.

Best Regards,
Suzanne Perry-Riehm
