Post-translational modifications(PTM) are essential to proteins in many ways, including improvement of stability, correct folding and regulation of functions. Lysine acetylation, as one kind of PTMs found in three domains of life, implicates in multiple cellular processes including central metabolism, transcription, translation, cell morphology, cell cycle, signal transduction, stress response and the infection of pathogenic microorganism. Though studies about acetylation mainly focus on eukaryotes, with th...
