KEGG Pathway - A circle includes many compounds

Question

[zrongstudent]

Dear all:

Recently I'm learning KEGG Metabolic Pathway(e.g. sil00130), but I find there is a circle that is a set of many compounds, I don't know whether this circle involves a metabolic reaction(because I can't find it in kgml file), and what meaning of this circle is. If there is anybody understand that, it will be helpful. Greatly appreciate any help.

Thanks.

The tooltip name simply enumerates a couple of possible compounds (actually, one generic name for a variable <n> and two common instantiations for specific fixed <n>s) for different values of <n> in the <n> bracket [] of the structure drawing.

Got it! Thanks! But I find the kgml file excludes this reaction, does its missing affect the result of constructing metabolic network? And if it does, how can I add it to my network accurately?
