Abstract

The genes and encoding the first two enzymes of the proline biosynthetic sequence in Escherichia were subcloned from a ColE1 hybrid plasmid containing 23·3 kilobases of genomic DNA. and are contiguous and constitute a single operon transcribed in the direction . The operon is contiguous with the gene . Hybridization experiments showed no homology between of and the other regions of the genome or with the DNA of several other bacterial species.
