Loss of MtrB results in a global shift in the S. venezuelae NRRL B-65442 metabolome. Principal component analysis on the wild-type (blue dots) and three independently isolated mtrB mutants (red, green, and orange dots). Data from ΔmtrB mutant strains clearly group together, and are distinct from data obtained from the wild-type while variations within each group are comparably small.
