LC-MS analyses. (A) Mass spectrum of ABA standard showing a predominant peak at m/z 247.1335 (M+H+-H2O). (B) Ion traces for m/z 247.1335 with a width of 30 ppm of metabolites extracted from wild-type ATCC 58025 (dotted line) and replacement mutants ΔBccpr1-16 (dashed line) and ΔBcaba1-27 (full line). (C) Ion traces for m/z 235.172 with a width of 30 ppm of metabolites extracted from wild-type ATCC 58025 (dotted line) and replacement mutant ΔBcaba1-27 (full line). (D) Mass spectrum of the unknown metabolite from replacement mutant ΔBcaba1-27 eluting at 4.854 min.
