Detailed Description

The ProteinProteinCrossLink struct represents a cross-link between two peptides in OpenPepXL.

This struct completely defines a cross-link linking two peptides. It contains the two peptides alpha and beta as AASequences, the positions that are linked in each peptide, the mass and name of the linker and terminal specificities to distinguish linkers attached to side chains of the terminal residues from linkers attached to the termini themselves. The beta peptide can be an empty AASequence object in case of a mono- or loop-link. Used to represent a theoretical candidate for generation of theoretical spectra and matching to experimental spectra.
