Figure 4.
Sequence alignment of human galectin-1, -3, -7, -4N, -4C, -12N, and -12C. Sequences were aligned using ClustalW and visualized with Jalview (102). Each carbohydrate recognition domain (CRD) consists of 135 to 165 amino acids, arranged on two antiparallel β-sheets composed of six (F′-F5 and S1-S6) β-strands. Residues were colored by identity score ranging from blue (identical) to white (nonidentical). Highly conserved amino acid residues essential for recognition are highlighted in red, and specific residues relevant for recognition are marked in orange.
