AbstractReversible Nε-lysine acetylation has emerging as an important metabolic regulatory mechanism in microorganisms. Herein, we systematically investigated the site-specific and kinetic characterization of enzymatic (lysine acetyltransferase) and nonenzymatic acetylation (AcP-dependent or Acyl-CoA-dependent), as well as their different effect on activity of metabolic enzyme (AMP-forming acetyl-CoA synthetase, Acs). It was found that Bacillus subtilis acetyl-CoA synthetase (BsAcsA) can be acetylated in vitro either catalytically by lysine acetyltransferase BsAcuA and Ac-CoA (at low concentration), or nonenzymatically by Ac-CoA or AcP (at high concentration). Two distinct mechanisms show preference for different lysine acetylation site (enzymatic acetylation for K549 and nonenzymatic acetylation for K524), and reveal different dynamics of relative acetylation changes at these lysine sites. The results demonstrated that lysine residues on the same protein exhibit different acetylation reactivity with acetyl-phosphate and acetyl-CoA, which was determined by surface accessibility, three-dimensional microenvironment, and pKa value of lysine. Acetyl-CoA synthetase is inactivated by AcuA-catalyzed acetylation, but not by nonenzymatic acetylation.

From 33 citing papers with measurable signal
Ranked by citation count — the same ordering the engine uses when summing log1p(Cq) over citers.
DataRank blends this paper's own citation count with the influence of the papers that cite it. Here, roughly 37% comes from its base citations and 63% from the citation network (33 citing papers contributed measurable signal).
Citers are pulled from OpenAlex sorted by cited_by_count:descand capped per paper, so when the cap binds we keep the highest-signal references and the score is reproducible across reruns.
