Sequence characteristics and protein properties of LHCs. (A). The distribution of normalized LHC family members across the selected species is illustrated. The heat map has undergone Z-score standardization processing, and the numbers represent the original LHC quantities. (B). Characteristic features, including molecular weight, isoelectric point, and the number of amino acids for the four subfamilies are presented. The calculation formula of the Coefficient of Variation (CV) is: CV = (Standard deviation/mean) × 100%. Comparison of typical values: The typical molecular weight of LHCB is 27.8 kDa. The typical molecular weight of LHCA is 25.2 kDa. Calculation of absolute difference:27.8 kDa–25.2 kDa = 2.6 kDa. Percentage difference calculation: (2.6/25.2) × 100% ≈ 10.3%. (C). Within the LHC proteins sequences, two conserved motifs are identified, with ExxNxR being the most highly conserved.
