Question Mass Mapping experiment



Hi everyone.
Can i have some help with answering below question? Would greately appreciate as my exam is next week.


During a mass mapping experiment, two proteins were identified that shared a common m/z profile for all ions, with the exeption of one pair.

Protein1 573.40, 679.44, 916.50, 1064.50, 1245.61, 1698.83, 2275.36
Protein2 573.40, 679.44, 916.50, 1064.50, 1245.61, 1714.89, 2275.36

What does this tell you about the two proteins and how mightthe two peptides of different m/z differ?
