WebETD, along with higher energy collisional dissociation (HCD) MS, was employed to assign the PTMs of the HCF-1 protein isolated from HEK293T cells. These include 19 sites of O-GlcNAcylation, two sites of phosphorylation, and two sites bearing dimethylarginine, and showcase the residue-specific, PTM complexity of this regulator of cell proliferation. WebSep 1, 2009 · The lys (gly-gly) modification (K(GG)) was mapped based on the mass difference between the y6 and y7 ions in the spectrum derived from the doubly charged … WebAug 19, 2024 · In the best cases, electron transfer dissociation (ETD)-based TD allowed for 30–35% sequence coverage attained of a commercial IgG [12, 16, 17], due to the rigidity coming from the disulfide bridges across each IgG domain. One way to circumvent TD MS analysis shortcomings is to reduce the size of the protein. ... HCD, and ETD in MD MS of … bingley body shop
