Expression level changes of proteins that were involved in nicotine degradation.

The expressions of proteins Porin, Mfs, SpmC, SpmA, Sapd, Pnao, NicA2, HspA, HspB, and NicA1 were identified and detected by MS-based spectral counting. The plot shows expression level of various proteins in different media: red, nicotine medium; blue, glycerol medium. Bars indicate the average ± s.e.m of the normalized spectral counts (y axis).
