• A portion of this plasmid was derived from a plasmid made by: Previously, we PCR amplified the lig gene from pRBL (Ren et al., 1997; PMID: 9305776). The optimized pprA gene, with flanking restriction sites (BamHI and SpeI), was synthesized by DNA 2.0 (Menlo Park, CA, USA).

For expression, E. coli DH5a-E cells harbouring each expression vector were grown at 37°C in LB broth containing chloramphenicol (34 µg.ml-1), to OD600 ~ 0.6. IPTG (0.4 mM, final concentration) was added as an inducer, and protein over-expression was at 28°C for 16-18 h.
