Table 1. Distribution of B. infantis proteins in cell wall or cytosolic fractions.
| Location | Proteins identifieda | Theoretical cell wall/membrane associated proteinsb |
| Cell wall association (CWA) | 196 | 108 |
| Cytosol (CYT) | 93 | 2 |
| Unidentified (UI) | 281 | 17 |
| Total | 540 | 127 |
a
Number of the protein for which the location was determined by the score system (See Materials and Methods).
b
Theoretical cell wall/membrane associated proteins were determined by the Signal prediction by SignalP 2.0 HMM and the transmembrane helices prediction by TMHMM2.0. Bioinformatic information including pfam classification was obtained from the Integrated Microbial Genomes database.
