protein, cleavage C-terminal mass changeSyntaxThis value is a floating point number represented by a character string Notes
DescriptionThis value represents the mass added to the C-terminus of a peptide after undergoing peptide bond cleavage by a chemical or enzymatic reagent, in Daltons. The default value is the mass change associated with hydrolytic cleavage in normal water. see also: protein, cleavage N-terminal mass change | protein, N-terminal residue modification mass | protein, C-terminal residue modification mass X!
