cLPCAT3 structural analysis reveals a condition-dependent dimerization state. (A) X-ray crystal structure of cLPCAT3 (PDB ID 7EWT) solved without substrates bound. For comparison to the dimer structure from cryoelectron microscopy, the rotated image on the right is presented in the same orientation as the right (blue) subunit of the dimer in left side of panel (B) Dimeric structure of cLPCAT3 solved by cryoelectron microscopy (PDB ID 7F40) with arachidonoyl CoA (orange) and 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC, lime green) bound to each monomer. Arrows on the cytosolic top view indicate the lateral/horizontal tunnel for acyl acceptor entry. Figure created using Biorender.
