The query of haloalkane dehalogenase (DhaA) from Rhodococcus strain TDTM0003 with UniProt ID P59336 yielded 22,567 sequences in EnzymeMiner. This extensive search resulted in the creation of a dataset named HLD I-IV. To further refine the results, we preprocessed the resulting MSA against the DhaA query by removing protein sequences and positions with too many gaps. This step narrowed down the size of the alignment to 12,053 sequences and 299 positions, which were used for training.
