Depositor Comments

This plasmid utilizes the NIsin Controlled Expression (NICE) system. NICE® is a registered trademark of NIZO food research BV, P.O.Box 20, 6710 BA Ede, The Netherlands.

pMSP3535VA contains the Nisin-inducible PnisA promoter, and the pVA380-1 replicon for expression in gram-positive bacteria.

For protein expression in E. faecalis, induce with 10-25 ng/mL nisin (Sigma, N-5764). See associated article for instructions on how to make nisin solution.

Note: Nucleotide sequence encoding the signal sequence and one-third of the mature NisA (nisin) peptide remains associated with the PnisA promoter. The depositing laboratory recommends adding of a Stop codon to the 5' end of inserted sequences to avoid unintentional gene fusions.

Note: The theoretical full sequence uploaded here is NOT fully accurate - the NheI site at position 4414 has been lost, along with approximately 500bp of sequence in this region (compare the depositor's uploaded maps). The actual size of this plasmid is 8278 as listed here. The depositing lab has not resequenced the region in question, but the discrepancy does not affect plasmid function.

Note: This plasmid has been shown to accumulate deletions when replicated in E. coli (or gram-negative bacteria). Screening transformants by restriction digest is recommended.

Addgene's quality control sequencing finds discrepancies with the depositor's provided sequence, but they are not thought to affect plasmid function.
