Web9 Oct 2024 · One of the most common modifications is glycosylation – the addition of sugar monomers and polysaccharide chains to proteins. The most dramatic is probably phosphorylation, attachment of the phosphate groups that makes kinases active, triggering regulatory cascades in the cells. [1] The Importance of Post-translational Modification WebTMPRSS13, a member of the type II transmembrane serine protease (TTSP) family, harbors four N-linked glycosylation sites in its extracellular domain. Two of the glycosylated residues are located in the scavenger receptor cysteine-rich (SRCR) protein domain, while the remaining two sites are in the catalytic serine protease (SP) domain. O-linked glycosylation is the attachment of a sugar molecule to the oxygen atom of serine (Ser) or threonine (Thr) residues in a protein. O-glycosylation is a post-translational modification that occurs after the protein has been synthesised. In eukaryotes, it occurs in the endoplasmic reticulum, Golgi apparatus and occasionally in the cytoplasm; in prokaryotes, it occurs in the cytoplasm. Several different sugars can be added to the serine or threonine, and they affect the … table mismatch
