Figure 1

Functional hierarchy used to annotate B. subtilis. The left hand side of the figure shows the three level functional hierarchy. The columns on the right hand side correspond to the number of proteins annotated with the corresponding node or leaf for L. sakei and L. bulgaricus respectively. Columns 'annot.' correspond to the number of proteins annotated by human experts, columns 'process.' correspond to the number of proteins that are considered in this study (see text). In the latter case, for inner nodes, this number is given as the sum of the figures for the direct descendants and the number of proteins having the node (partial) annotation, within square brackets. For instance, for proteins of L. sakei annotated in class 2 "intermediary metabolism", there are 2 proteins with only the class 2 annotation and 215 with more detailed annotations, that are thus distributed in the daughter classes: 2.1 – 2.9.
