Phosphorylation is a highly effective mechanism for regulating the activity of enzymes and is the most common post-translational modification. Many eukaryotic and prokaryotic proteins also have carbohydrate molecules attached to them in a process called glycosylation , which can promote … See more Post-translational modification (PTM) is the covalent and generally enzymatic modification of proteins following protein biosynthesis. This process occurs in the endoplasmic reticulum and the golgi apparatus. … See more • ubiquitination, the covalent linkage to the protein ubiquitin. • SUMOylation, the covalent linkage to the SUMO protein (Small Ubiquitin-related MOdifier) See more • disulfide bridges, the covalent linkage of two cysteine amino acids • proteolytic cleavage, cleavage of a protein at a peptide bond See more • Protein targeting • Post-translational regulation See more Addition by an enzyme in vivo Hydrophobic groups for membrane localization • See more • citrullination, or deimination, the conversion of arginine to citrulline • deamidation, the conversion of glutamine to glutamic acid or asparagine to aspartic acid • eliminylation, the conversion to an alkene by beta-elimination of phosphothreonine and phosphoserine See more Protein sequences contain sequence motifs that are recognized by modifying enzymes, and which can be documented or predicted in PTM … See more WebAug 15, 2024 · Both phosphorylation and dephosphorylation are carried out by enzymes (e.g., kinases, phosphotransferases).
