The unit A of β-bungarotoxin lacked the Cys11‒Cys70 pair and were under global epigenetic regulation. (A) The ML phylogenetic tree and the amino acid sequence alignment of the GI-PLA2. (B, C) The expression characteristics of the many-banded krait GI-PLA2 in venom gland b and muscle c. Tracks from the top to bottom are H3ac counts (the red histogram), H3K27me3 counts (the navy histogram), the reads count of transcriptome (blue histogram) and gene structures (green blocks, where GI-PLA2 were indicated using red). Loops were displayed using arcs. Heatmaps implicated the contact frequency between chromosomal regions. The large square frames implicated the TADs and small square frame implicated peak loci.
