Serine Protease Variants Encoded by Echis ocellatus Venom Gland cDNA: Cloning and Sequencing Analysis

Figure 4

Amino acid sequence similarity between EoSP Variants and serine proteases from related vipers. The residues shaded in black correspond to residues that are identical to EoSP-01. The asteriks [*] represented the tweleve conserved cysteine residues. The catalytic traid His/Arg (67), Asp (110) and Ser (208) are represented in red circules. Activated peptide where the mature proteine cleaved is represented by green rectangle.
