Statistics of protein entries in dbOGAP. Left, Venn diagram showing the number of O-GlcNAcylated proteins and modification sites in the dbOGAP database. There are a total of 1163 protein entries in the database. A - Experimental O-GlcNAcylated proteins; B - Proteins with identified O-GlcNAcylation sites (G-sites); C - Proteins with identified phosphorylation sites (P-sites); D - Proteins with inferred O-GlcNAcylation sites based on orthologs with known O-GlcNAcylation sites. Right, Taxonomic distributions of experimentally determined O-GlcNAcylated proteins in dbOGAP. Numbers shown in the pie chart are percentage of proteins in given species over the total number of proteins in the database. "Other" species include Bos taurus (3 protein entries), Gallus gallus (2), Coturnix coturnix japonica (1), Rhea americana (1), Macaca mulatta (1) and Viruses (3).
