Figure 4: The sequence of arylacetamide deacetylase identified in the SDS-PAGE gel slices with nos. 18 (0.5-mm thickness, a) and 34 (0.25-mm thickness, b). Proteins score greater than 56 were significant. Amino acid residues definitively identified from analysis of fragment ions by MALDI-TOF PMF are in bold. Common peptides are shown in ©, and proteotypic peptides observed only in slice 34 are underlined in (b) and shown in (d) at the bottom.
