Quantitation of intracellular
amino acids in a ΔserBE. coli strain extracts. (A) Measured amino acid
quantities of select amino acids in K12 BW25113 WT vs ΔserBE. coli grown in LPM media and LB
media. (B) Measured amino acid quantities of ΔserBE. coli grown in LPM media (light gray), LB media
(dark gray), LPM with 5 mM pSer (light blue), LB with 5 mM pSer (dark
blue), LPM with 5 mM pThr (light violet), LB with 5 mM pThr (dark
violet), LPM with 5 mM pTyr (light orange), and LB with 5 mM pTyr
(dark orange). Error bars were calculated using the 95% confidence
interval with n = 5.
