In vitro expression of Lac-PTS and tagatose 1,6-bisphosphate aldolase genes from Lactococcus lactis subsp. cremoris plasmid pDI-21.
A 4.4-kb EcoR1-EcoR1 DNA fragment from the Lactococcus lactis subsp. cremoris plasmid pDI-21 encoded the tagatose 1,6-bisphosphate (TBP) aldolase gene and the Lac-PTS genes. In vitro transcription-translation using Escherichia coli S30 extract showed the synthesis of 41,000-, 23,000- and 12,000-dalton proteins which correspond to the TBP-aldolase, Lac-PTS enzyme II, and factor III proteins respectively.
