Takahashi H, et al. (2006) Nucleocytosolic acetyl-coenzyme a synthetase is required for histone acetylation and global transcription. Mol Cell 23(2):207-17
Abstract: Metabolic enzymes rarely regulate informational processes like gene expression. Yeast acetyl-CoA synthetases (Acs1p and 2p) are exceptional, as they are important not only for carbon metabolism but also are shown here to supply the acetyl-CoA for histone acetylation by histone acetyltransferases (HATs). acs2-Ts mutants exhibit global histone deacetylation, transcriptional defects, and synthetic growth defects with HAT mutants at high temperatures. In glycerol with ethanol, Acs1p is an alternate acetyl-CoA source for HATs. Rapid deacetylation after Acs2p inactivation suggests nuclear acetyl-CoA synthesis is rate limiting for histone acetylation. Different histone lysines exhibit distinct deacetylation rates, with N-terminal tail lysines deacetylated rapidly and H3 lysine 56 slowly. Yeast mitochondrial and nucleocytosolic acetyl-CoA pools are biochemically isolated. Thus, acetyl-CoA metabolism is directly linked to chromatin regulation and may affect diverse cellular processes in which acetylation and metabolism intersect, such as disease states and aging.
