摘要: With the advent of novel mass spectrometry techniques such as Orbitrap MS, it is possible to determine exact molecular formula an unknown molecule solely from its isotope pattern. But for protein spectrometry, one facing problem that many peptides have exactly same even when ignoring order amino acids. In this work, we present efficient method acid composition peptide formula. Our solution based on efficiently enumerating all solutions multi-dimensional equality constrained integer knapsack problem.
