• PLAC4-PBI promoter does not express in E. coli allowing toxic genes to be cloned prior to their expression in yeast.
• Universal MCS lies downstream of DNA encoding CBD and PLAC4-PBI promoter.
• Acetamidase expression for non-antibiotic selection in K. lactis.
• Ampicillin resistance for propagation in E. coli.
• Permits expression of CBD-tagged fusion proteins and their one-step purification directly from growth medium
Description:
Vector pKLCF-c contains the strong K. lactis PLAC4-PBI promoter (1), DNA encoding theK. lactis Cts1p chitin-binding domain (2), a universal multiple cloning site (MCS), the K. lactis LAC4 transcription terminator (TT), and a fungal acetamidase selectable marker gene (amdS) expressed from the yeast ADH1 promoter (PADH1). An E. coli replication origin (ori) and ampicillin resistance gene (ApR) is present for propagation of pKLCF-c inE. coli. SacII or BstXI linearized pKLCF-c integrates into the LAC4 locus of the K. lactisgenome upon transformation of K. lactis competent cells.

pKLCF-c is isolated from E. coli strain ER2268 by a standard DNA purification procedure.
