Peptide mapping of the tm0958 ORF gene products. MALDI mass spectra of the in-gel tryptic digests of the (A) 32 kDa and (B) 20 kDa products of the tm0958 ORF. Peptides observed in (A) that were not observed in (B) are indicated. (C) Mapping of the peptides from (A) onto the tmRBP amino acid and DNA sequence. Mapped peptides are underlined in black, met142 is underlined in green, and the alternate ribosome binding site is underlined in red.
