title: Soluble protein expression in E. coli cells using IgG-binding domain of protein A as a solubilizing partner in the cold induced system.
abstract: We constructed a cold induced expression vector in Escherichia coli cells that consists of a histidine tag sequence for nickel chelate affinity purification, IgG-binding domain of protein A (ZZ-domain) and the multiple cloning sites. The role of ZZ-domain as a solubilizing partner at 15 degrees C was demonstrated by expressing the imidazopyrazinone-type luciferases of Renilla, Oplophorus, Gaussia, and Vargula (Cypridina) as well as the calcium-binding photoproteins and firefly luciferase. The fused protein with ZZ-domain was expressed efficiently as a soluble form in the cytoplasm of E. coli cells at low temperature.
