Straightforward and de novo peptide sequencing by MALDI-MS/MS using a Lys-N metalloendopeptidase.
In this work, we explore the potential of the metalloendopeptidase Lys-N for MALDI-MS/MS proteomics applications. Initially we digested a HEK293 cellular lysate with Lys-N and, for comparison, in parallel with the protease Lys-C. The resulting peptides were separated by strong cation exchange to enr...
