Fig. 2.

Normalized protein abundances of PobA, VanA, and VanB as measured by MS-based proteomics. Cultures were grown in M9 minimal medium containing p-coumarate (for PobA) or ferulate (for VanA and VanB) and either glucose or acetate. Cell pellets were lysed and the proteins were digested with trypsin and subjected to analysis by LC-MS/MS. Each value represents the average of three biological replicates. The error bars represent standard deviation of the measurements. (A) Normalized abundances of PobA, (B) Normalized abundances of VanA, (B) Normalized abundances of VanB.
