![]() ![]() The classification result,of P putida strains was highly comparable to those based on a conventional DNA sequence analysis. Using this method, the phylogenetic classification of a total of 16 strains of Pseudomonas pulida was demonstrated. Similarly, we can talk about the Kurtosis (a measure of Tailedness) of the distribution by simply looking at its Q-Q plot. 7 q qqqqqqqq q qqqqqqqqq qqqqq qq qqqqqqqqqqqqqqqqqqqqqqqqq qqqqqqq qqqq q qqqqqq. The profile of the mass differences of ribosomal proteins was processed by cluster analysis, and generating a phylogenetic tree. Such sequence variations could be detected as mass differences in the MALDI mass spectra. Through the characterization of ribosomal proteins of genome-sequenced lactic acid bacteria (LAB), a guideline for selecting reliable biomarkers used for the rapid identification of LAB by MALDI-MS was proposed Although the amino acid sequences of ribosomal proteins is highly conserved, slight sequence variations of some ribosomal proteins can occur at the strain level, reflecting different phylogenetic evolution rates. q qqqqqqqqq q qqqqqqq qqqqqqqqqq qqqqq qq q qqqqq q qqqqqqqq qqqqqqq qqqqqqqq qq qqqqqqqqqqq qq qqqq qqqqq qqqqqqqqqq qqqq qqq qqqqqqqqqqqqqq qqqqqqq q q q. To verify the actual state of sequence information of ribosomal proteins registered in the protein databases, a simple intact protein analysis using only cell lysate without the purification of ribosomal proteins was developed. qq q q q q qqq qqqqqqqq q qq qqqqqqq q qq qqqqqqqqqqq qq qqqqq q. qqq qqqq qq q qqqqqqqq qqqq qqqqqq q qqq qq qqqqq q q qqqqqqqqqqqqqqqqqqq q q qq q qqq q q q q q qq q qqqqqqqqqq q q qqq qqqqq q qqqqqq q qqqq q qqqqqqqqq q. qqqqqqqqqqqqqqqqqqq qqq q qqqqqq qqqqqqqqqqqqqqqqqqqqq q qqq qqqqqqqqqqqqqqqqqqqqq qqqqqq qqqqq q qqqqq qqqq qqqqq qqqq qqqqqq qqqqqqqqqqqqqqqqqq qqqqqq. 50 different kinds of ribosomal proteins were used as biomarkers for bacteria characterization. In this study, a simple, rapid, and highly reliable method for the identification and classification of bacteria by matrix-assisted laser desorption/ionization-mass spectrometry (MALDI-MS) was developed. qq qq qqqqq q q qqqq q qq q qq q qqq q qq q qq q q qqqqqqqqqq q q q qq q q qqqqqq q q qqqqq qq qqqqqqqqqqqqq q q q q q qqqqqqqqq qq q qqqqqqq q q q qq q q q.
