PPT-Ubiquitination ® Post-translational modification of a protein by the covalent attachment

ubiquitin monomers The most prominent function of ubiquitin is labeling proteins for proteasomal degradation Ubiquitination also controls the stability function and intracellular localization of a wide variety of proteins . The classic principle of . protein folding. is that all the information required for a protein to adopt the correct three-dimensional conformation is provided by its amino acid sequence..

Expression of essential genes is required under all growth conditions but the expression of other genes is conditional. Thus, cells must regulate gene expression using transcription regulation to determine which genes are transcribed and to what extent. Transcription regulation is the most common mechanism to control gene expression in bacteria. quantitation. . -.
