Alignment of amino acid sequences encoded by transcripts 64201-seq1, 64201-seq2, and 62762. The alignment was carried out using Clustal Omega (http://www.ebi.ac.uk) and visualised using Jalview (http://www.jalview.org). Residues are colored according to conservation of sequence identity (dark blue: 100 % conserved). Black boxes represent positions of ATP-binding motifs conserved throughout the ANL superfamily [33], and red boxes represent luciferin-binding residues from the beetle luciferase [62, 63]. The residue marked with a ‘#’ plays a key role in the firefly luciferase adenylation half reaction, and the residue marked with a ‘*’ plays a key role in the oxidation (light-producing) half reaction [64]
