Fig. 7From: Subtractive assembly for comparative metagenomics, and its application to type 2 diabetes metagenomesThe truB-ribF operon identified by subtractive assembly as associated with T2D. a There are three domains in the operon: TruB encoded by truB; and flavokinase and FAD synthetase encoded by ribF. The flavokinase and FAD synthetase constitute the bifunctional prokaryotic riboflavin biosynthesis protein. b The genes truB and ribF in this operon are confirmed by read mapping. Reads mapped to the proper pair are colored in blue and mapped singletons are colored in green Back to article page
