Collagen Structure and Stability Annual Review of Biochemistry (2009) 78:929-958
The following Modification-Abundance (M-A) diagrams show the number of times a residue has been observed with a particular PTM in a peptide-to-spectrum match in GPMDB, as a function of the residue's position in the corresponding protein sequence. Note that the Y-axes have log scales.
