Fig. 2From: Bioinformatic analysis of structures and encoding genes of Escherichia coli surface polysaccharides sheds light on the heterologous biosynthesis of glycansFrequency of donor and acceptor among different antigens. The location of each dot indicates the donor and acceptor of a linkage, its size indicates the number of link types, and the color indicates its frequency of occurrence in O antigens (A) or K antigens (B).
