Taken collectively, even though both sulfation and nitration prefer to co-occupy with phosphorylation, the sulfationML277 Autophagy phosphorylation and nitration-phosphorylation crosstalks may possibly preferentially happen in numerous pathways. The experimentally identified PTM tyrosines which includes 273 sulfation, 1050 nitration and 24,242 phosphorylation web sites were being utilized for that assessment. On top of that, 17,015 and 25,306 predicted sulfation and nitration web sites in phosphorylated substrates ended up also analyzed, when 2913 and 3689 phosphorylation web pages have been predicted PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/28588322 to be sulfation- and nitrationphosphorylation crosstalk internet sites. Using these datasets, we 1st analyzed the situation distributions of modified tyrosines. In the outcome, known sulfation internet sites preferentially arise at N-terminal or C-terminal although not center of proteins, while predicted sulfation websites somewhat prefer to identify at C-terminal, too as other types of tyrosine modifications and their crosstalks (Fig. 5a). Also, a variety of structural characteristics have been analyzed. Within the final results of secondary structures, it absolutely was noticed that the two regarded sulfation and nitration internet sites are enriched in Coil, while predicted nitration web-sites are deprived in Coil and sulfation web pages are enriched in b-Strand PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/25816071 (Fig. 5b).
