| Abstract: | The RNA polymerase binding sites present along a DNA segment encompassing the glnA, glnL, and glnG genes have been identified in a hybrid plasmid carrying this chromosomal region of Escherichia coli. The DNA sequence was determined of an 817 base pair segment that contains the region coding for the first 42 amino acids of the NH2-terminal and of the glnA structural gene, as well as its regulatory region. Analysis of this nucleotide sequence revealed three probable RNA polymerase recognition sites, imperfect palindromes, inverted repeats, and direct repeated sequences. |
