To construct pMAL-EFSep the gene encoding EF-Sep, was cloned between the NdeI and BamHI sites in the pET20b plasmid (Novaven) to
add a C-terminal His6 tag. This fusion construct was then PCR-amplified using primers adding MfeI and PstI restriction sites. The PCR product was cloned in-frame between EcoRI and PstI in pMALc2x (New England Biolabs) to add an N-terminal maltose binding protein (MBP) tag.
To prevent possible enzymatic dephosphorylation of O-phospho-L-serine (Sep) in vivo, the gene encoding phosphoserine phosphatase (serB), which is catalyzing the last step in serine biosynthesis, was deleted from Escherichia coli strains Top10 (Top10∆serB - Addgene #34928) and BL21 (BL21∆serB - Addgene #34929). These strains are required hosts when using this plasmid.
These plasmids were created by your colleagues. Please acknowledge the Principal Investigator, cite the article in which the plasmids were described, and include Addgene in the Materials and Methods of your future publications.
