Comprehensive library of ribosomal proteins of different microbial species

Ribosomal proteins are building blocks of ribosome, and are thus essential proteins of any cell. Work reported in the literature has eluded to the important roles ribosomal proteins in ensuring cell viability, as well as encoding phylogeny of a species in addition to 16S or 18S rRNA. It is such phylogenetic significance that lends ribosomal protein use in different microbial identification protocols such as matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS) or other soft ionization mass spectrometry proteomics approaches. To support this role of ribosomal proteins, this work collated the ribosomal protein complement of different microbial species to help build a comprehensive library of ribosomal proteins useful to help annotate ribosomal protein mass peaks. Concatenating protein name, amino acid sequence, nucleotide sequence, number of residues and molecular weight, the library should find use in various methodologies that require annotation of the protein mass peaks.
