Numerous studies focused on the aggregation and/or amyloidogenic properties of AcPs suggest the importance of edge-beta-strands in the process. In this work, we present the first crystallographic structure of Escherichia coli AcP (EcoAcP), showing notable differences with the only available NMR structure for this enzyme. EcoAcP is crystalised as an intertwined dimer formed by replacing a single C-terminal beta-strand between two protomers, suggesting a flexible character of the C-terminal edge of EcoAcP. Despite numerous works where AcP from different sources have been used as a model system for protein aggregation, our domain-swapped EcoAcP structure is the first 3-D structural evidence of native-like aggregated species for any AcP reported to date, providing clues on molecular determinants unleashing aggregation.
