Cryo-EM maps for PvdL-E2-C3-A3-PCP3 and related constructs

This dataset contains the Cryo-EM density maps for the PvdL cross-module constructs used in our study, including PvdL-E2-C3-A3-PCP3, PvdL-PCP2-E2-C3-A3-core, and PvdL-E2-C3-A3-core-R3393A.These maps were used to elucidate the tetrahydropyrimidine cyclization mechanism and stereochemical control by the PvdL-C3 domain. This dataset supports our research published in <b><i>Nature Synthesis</i></b>: "<b>Analysis of heterocycle formation and stereochemical control by a nonribosomal peptide synthetase condensation domain."</b> DOI: https://doi.org/10.1038/s44160-026-01014-7The final processed maps and atomic models have been deposited in the Electron Microscopy Data Bank (EMDB) and the Protein Data Bank (PDB) under accessions EMD-64387, EMD-62988, EMD-62989, EMD-62990, and PDB 9UP2, 9LCO, 9LCP, and 9LCQ, respectively.
