“…We found 253 positions of 307 PTMs, reported in 30 works [ 5 , 6 , 12 , 15 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 ] focusing on fibrinogen modified either in vivo or in vitro (see Figure 2 and Table S1 ). The positions of PTMs are reported according to the mature chains, i.e., sequences without a signal peptide.…”
