AbstractHuman acetyl-CoA carboxylases (ACCs) catalyze the carboxylation of acetyl-CoA, which is the rate-limiting step in fatty acid synthesis. The molecular mechanism underlying the dynamic organization of ACCs is largely unknown. Here, we determined the cryo-EM structure of human ACC1 in its inactive state, which forms a unique filament structure and is in complex with acetyl-CoA.

AbstractPropionyl-CoA carboxylase (PCC) and 3-methylcrotonyl-CoA carboxylase (MCC) are biotin-dependent carboxylases (BDCs) that catalyze the metabolism of odd-chain fatty acids, cholesterol, and specific amino acids. For human PCC and MCC, only a low-resolution (15 Å) three-dimensional structure of human PCC has been reported. Here, we report high-resolution (2.29–3.28 Å) cryo-EM structures of human PCC and MCC holoenzymes in their apo and acetyl-CoA and propionyl-CoA-bound states.

In the version of this article initially published, an overview sentence was missing at the beginning of the Fig. 3 legend: “Environmental impacts under different scenarios (left) and the projected changes in the FoodSystem scenario relative to the Reference scenario in 2060 (right)”. The sentence has been inserted in the HTML and PDF versions of the article.
