The pattern of gene variation in the 25 gene clusters.

<p>The genes for each cluster are presented in map order. Cells for genes present more than once are coloured. No colour means that the sequence is unique. Genes within a column with the same color have the same sequence. There are 5 genes (<i>gnaB</i>, <i>ugd</i>, <i>mnaA</i>, <i>wafT</i>, <i>wagP</i>) present at 2 loci within the gene clusters, so each in two columns and also given the same colour. Superscripts: .a: Pyruvyltransferase, b: Function unknown, c: Acyltransferase. Others are glycosyltransferases or pathway genes. The column “Number of unique genes” gives the number of GT and pathway genes plus <i>wzx</i> and <i>wzy</i> HGs that are unique to that PSgc.
