Fig. 2From: Conversion of methionine biosynthesis in Escherichia coli from trans- to direct-sulfurylation enhances extracellular methionine levelsE. coliΔmetAB is auxotrophic for methionine. WT and ΔmetAB were grown in a minimal MOPS medium with or without supplementation of external methionine for 900 min at 37 °C. The legend shows supplemented methionine concentration in μg/mlBack to article page
