Inventory of the proteins in Neisseria meningitidis serogroup B strain MC58.

A protein inventory of Neisseria meningitidis strain MC58, a meningococcal strain belonging to the serogroup B, was performed by proteomics. A differential extraction procedure was employed and 238 protein species were identified by 2D mini-maps and MALDI-ToF analyses. In this catalog, we detected protein products from 33 genes, which were not yet annotated in previous N. meningitidis proteomic studies. This approach is suitable for high-throughput studies on differential expression of N. meningitidis genomes.
