SwaI forms a dimeric alpha/beta structure with each subunit having a central credle-like mixed beta-sheet with two helices packed on its concave side and a C-terminal helix contributing to the dimer interface [1]. SwaI has a significant similarity to other restriction endonucleases such as HincII, NlaIV, HindIII, EcoRV and others.
