The nucleotide sequence of the rpoD gene (encoding the primary sigma-70 (sigma 70) subunit of RNA polymerase) from Escherichia coli C was determined. This gene differs from that of E. coli K-12 by a 30-bp deletion and five single-bp substitutions, resulting in a sigma 70 subunit with three amino acid (aa) changes and a deletion of ten acidic aa.
测定了来自大肠杆菌C的rpoD基因（编码RNA聚合酶的主要σ-70（σ70）亚基）的核苷酸序列。该基因与大肠杆菌K-12的基因不同，存在一个30bp的缺失和五个单碱基替换，导致σ70亚基有三个氨基酸（aa）变化以及十个酸性aa的缺失。
