Model domain organisation of (a) fruit bromelain (sequences with the accession number of BAA21848 in the NCBI Genbank database and 352 amino acids) and (b) stem bromelain (sequences with the accession number of CAA08861 in the NCBI Genbank database and 357 amino acids). α-helix domain (domain I29 at the N-terminal region) is colored in green, β-sheet domain (domain peptidase C1 at the C-terminal region) is colored in orange. The catalytic amino acids of both models are represented as sticks (Reproduced with permission from [13], Elsevier, Amsterdam, The Netherlands, 2018).
