Can proteins be acetylated
Deacylations "play crucial roles in gene transcription and most likely in all eukaryotic biological processes that involve chromatin". Acetylation is one type of post-translational modification of proteins. The acetylation of the ε-amino group of lysine, which is common, converts a charged side chain to a neutral one. Acetylation/deacetylation of histones also plays a role in gene expression and cancer. These modi… WebJun 26, 2024 · The non-acetylated variant is destabilized explicitly under drought stress, suggesting a stabilizing impact of NTA on plastidic proteins (3B). NTA by the NatA complex can affect protein turnover by modulating folding or aggregation of substrates (Arnesen et al., 2010; Holmes et al., 2014) (4). Unfolded proteins are depicted as lines, while ...
