In bacteria, the ankyrin-like protein AnkB helps overcome stress by regulating catalase activity when expressed under stressful conditions. As the structural properties of AnkB are largely unexplored, our understanding of various AnkB-mediated functions in bacteria remains limited. In the present study, we describe the structure of AnkB from Acinetobacter baumannii, hereafter referred to as "AbAnkB," which has a unique tertiary configuration compared with that of other ankyrin domain-containing proteins. Structural analysis revealed that AbAnkB has a relatively long loop between AKR3 and AKR4 and an oppositely positioned α 8 helix. Based on amino acid conservation and protein surface analyses, we identified a hydrophobic patch that might be critical for the function of AbAnkB. To the best of our knowledge, our study is the first to report the structure of a bacterial AnkB protein; our findings will markedly enhance our understanding of its functions in bacteria.
