Abstract:Bombyx mori is the model insect of Lepioloptera with diapause during the egg stage, and the activation of diapause eggs is closely related to the biological clock protein TIME-EA4. TIME-EA4 has stable Cu/Zn SOD activity and one-time transitory ATPase activity. Numerous studies have focused on the structural and functional characteristics of TIME-EA4. The molecular evolution of this protein has received little attention. In this study, bioinformatics methods were used to analyze the evolutionary trace of TIME-EA4. The results showed that 91.2% of the important amino acid residues in TIME-EA4 were consistent with Cu/Zn SOD. However, there were some differences such as composition, amino acid residue polarity and bonded atoms in Cu/Zn ion binding sites were observed between these proteins.
