Fig. 6

Sequence coverage obtained for upper and bottom band in LC–MS/MS analysis. Red capital letters depicted amino acid (aa) sequence of peptides detected in upper and bottom TRAIL bands, black capital letters depicted aa sequence of peptides not detected in the both TRAIL bands, and black small letters depicted aa sequence of peptides detected only once in the bottom TRAIL band (Table 2). The upper and bottom TRAIL bands were obtained after SDS-PAGE analysis of TRAIL secreted by L. lactis (TRAIL+) bacteria
