Samples were taken from cultures after 4 hours incubation with 0.1 mM IPTG and 0.2% arabinose. Lane 1- Prestained protein marker (Fermentas), Lane 2- MGM100 pTrc-GroES- Cpn60.2; Lane 3: MGM100 pTrc-GroES-MKO, Lane 4: MGM100 pTrc-GroES- GroEL, Lane 5: MGM100 pTrc-GroES-JNL. (b) Native gel of JNL. Protein samples were taken from cells grown in LB with 0.2% glucose and induced with 0.1 mM IPTG for 5 hours. The GroEL native sample was from a purified stock. Lane 1: Native protein marker, Lane 2: GroES + Cpn60.2, Lane 3: GroES + JNL, Lane 4: GroES + GroEL. 173
