Left – cartoon representation of the DhaA haloalkane dehalogenase (PDB ID 1CQW). Right – part of the sequential representation of DhaA along with the information about secondary structures and five other proteins sequentially aligned to DhaA. The representation encodes the sequence identity of the DhaA with an automatically selected set of similar proteins. These proteins are sorted according to their similarity to DhaA. The enconding aims to convey the similarity in particular areas of the chain. Images were generated using the Aquaria tool by O’Donoghue et al.
