Recombinant plasmids with genes for the biosynthesis of alkaline phosphatase of Escherichia coli

Werner Boidol; Marianne Simonis; Michael Dr. Töpert; Gerhard Siewert

SummaryRestriction maps of several recombinant plasmids representing a section of the E. coli K12 chromosome 35,000 bp in size with the genes phoA, proC and phoB were prepared. The orientation of phoA and the exact position of its N-terminal end on this map were determined by identifying a subfragment which carried the phoA promoter and by determining the nucleotide sequence of a 160 bp portion of this subfragment comprising the codons for the N-terminal end of pre-alkaline phosphatase. From this DNA sequence the leader sequence of alkaline phosphatase which consists of 21 amino acids was derived.
