Fig. 4. Alignment of the deduced partial amino acid sequence for Dilocarcinus pagei V-type H⁺-ATPase B-subunit with representative invertebrate and vertebrate sequences, including green shore crab Carcinus maenas (AF189779), tobacco hornworm Manduca sexta (X64354), steelhead trout Oncorhynchus mykiss (AAD33861 and rat Rattus norvegicus (NM_057213). Alignment was produced using Multalin (Corpet, 1988) and GeneDoc software. Red color denotes identical amino acids in all sequences; yellow, identical aa in three of the five.
