Example of a basic set of selected biosynthetic units (BBUs). BBUs were defined as important intermediates in the biosynthetic pathways. In this context, the important intermediates are the molecules in the starting point of the pathway map, the molecules at the branches of the pathway, and the molecule generated immediately after the large structural change. We followed the distinction of solid and dashed arrows as drawn in the KEGG PATHWAY database. In general, solid arrows represent the reactions for which enzymes and reactions have been well characterized, and dashed arrows represent connections to other pathway maps, or reactions that are not yet well characterized
