Metabolite abundance of glycolytic and citric acid cycle intermediates in exponential (OD600 of 0.5) and stationary phase (OD600 of 3.0) of growth were measured for V. cholerae wild-type and ΔvcdRP, each harboring an empty vector control (pCtrl) or ΔvcdRP with vcdRP expression plasmids (pVcdRP and pVcdP). The y-axis represents the peak area of each metabolite determined by mass spectrometry. The main operative pathways including the fates of certain amino acids are color coded (yellow for glycolysis and blue for citric acid cycle).
