Levels of intermediates involved in l-lysine biosynthesis detected in strains JL-6, RG and RGI. The x-axes represent JL-6, RG and RGI. The y-axes represent the relative abundance of intermediate, which was calculated by normalizing the peak area of metabolite against the total peak area within the sample.
