Figure 1
Deposition rate of glycoproteins and protein–sugar complexes. This graph was produced using the publicly available search functions provided by the RCSB PDB (Bernstein et al., 1977), restricting each query to crystallographic structures. Structures containing saccharides were selected by the different `saccharide' chem_comp codes (represented by a red line on the graph), and structures containing N-glycosylation were selected by the ASNND2-NAGC1 LINK record (represented by a blue line); the latter figures do not reflect the total number, as at least 16 structures were found to have incorrect ASNOD1-NAGC1 LINK records. The total numbers of PDB structures per year (grey bars) have been plotted on a 1/10 scale (right axis) to make the 10% proportion stand out. |
