Texte intégralFlagella have been described as an important virulence factor for initial attachment to the host or to the surface of hospital equipment. However, how bacteria use their flagella to switch from a floating (planktonic) state to an immediately attached (sessile) state remains an open question. This transition involves flagellar mechanosensing or surface-sensing. It has been illustrated that lysine methylations in S. Typhimurium flagella facilitate bacterial adhesion to the surface or receptor via hydrophobicity. However, the study of the entire methylome, including non-histone methylation, remains a major challenge because of the lack of efficient methyl protein/peptide enrichment techniques. Here, to investigate protein methylation and its mechanisms in S. Typhimurium and its mutants, we applied two complementary strategies for methyl protein enrichment: aptamer-based enrichment technology and high pH SCXtips separation strategy. The specific DNA aptamers were obtained after performing several rounds of positive selection and one round of negative selection from a random oligonucleotide library through the FluMag-SELEX procedure. The selected ssDNA pools were sequenced and 10%, 11%, and 33% of redundant sequences for MML, DML, and TML, respectively have been observed. The highest redundancy was observed with oligonucleotides directed against TML. The interaction study of this aptamer with its target was then performed by the methods like ITC, PCR, and bead-based binding assays followed by mass spectrometry titration. The specificity was confirmed while the affinity was determined to be KD=2.48±0.14 mM. Then, the selected aptamer has been used as an enrichment tool based on the aptamer-bound beads method, in order to isolate methylated proteins or peptides on various cell lines. After the validation of our approach using a positive control (HEK293 cells), we identified 19 lysine methylation sites on 5 proteins from Salmonella Preliminary results from proteomic analysis confirmed that the selected aptamer was indeed able to distinguish and enrich methyllysine-containing proteins from S. Typhimurium strains and human cell lines. In parallel with this, the high pH SCXtips technology was performed as a complementary separation strategy when cultivating the strains in the hM-SILAC medium. Using this method, 23 unique methylation sites in ΔmetE, 51 unique methylation sites in ΔmetEΔmotAB, and 18 unique sites in ΔmetEΔfliB on 19 methylated proteins were identified. By comparing the differences in protein methylation, our results suggest that when bacteria lack motility, lysine methylations in bacterial proteins seem to be upregulated. Besides being methylated by the methylase FliB, a large number of methylation events could be regulated by other methylases
