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.
