Figure 4From: A novel carboxyl-terminal protease derived from Paenibacillus lautusCHN26 exhibiting high activities at multiple sites of substratesSDS-PAGE analysis of the P. lautus ctpA gene product. Protein molecular weight marker (Tiangen, Cat.No. DPP530S) (Lane 1), soluble proteins of E. coli BL21 (pET28a) (Lane 2) and E. coli BL21 (pET28a-ctpAp) (Lane 3) cultured and induced (ITPG, 1 mM) under the same condition at 20°C for 18 h, and purified recombinant P. lautus CtpA protein (Lane 4).Back to article page
