    Liquid extraction surface analysis (LESA) mass spectra of seven bacterial strains: Escherichia coli K-12, Escherichia coli BL21 mCherry, Pseudomonas aeruginosa PS1054, Staphylococcus aureus MSSA476, Streptococcus pneumoniae D39, Streptococcus oralis ATCC 35037, and Streptococcus gordonii ATCC 35105. All mass spectra were acquired immediately following incubation of the colonies at 37 °C, with use of the 40:60:1 acetonitrile–water–formic acid solvent system for Gram-negative bacteria and the 50:45:5 variant for Gram-positive bacteria. The streptococci were incubated under semianaerobic conditions for optimum growth; the remaining strains were grown in open air

    Recombinant AfIlv3A expression, purification and DHAD activity. A. Expression of recombinant Ilv3A protein. E. coli BL21 DE3 cells were transformed with pET30_Ilv3A, grown until OD600 > 0.5 and then incubated in the presence and absence of 0.5 mM IPTG for 20 h at 20°C. Ilv3A was purified from the bacterial lysate by immobilized metal ion affinity chromatography (IMAC). Protein fractions were separated by polyacrylamide gel electrophoresis on 4–12% Bis-Tris NuPage gels (Invitrogen) followed by staining with GelCode Blue staining reagent (Pierce). The molecular weights in kilo Daltons of marker proteins are indicated. Lane 1, E. coli cell lysate; lane 2, E. coli cell lysate following IPTG induction; lane 3, Ilv3A protein purified by IMAC. B. Dihydroxyacid dehydratase activity of recombinant Ilv3A. 2 µg Ilv3A was assayed in the presence of 0–60 mM L-threonic acid. Initial reaction velocities were calculated and plotted versus substrate concentration.
