大肠杆菌σ-70的第149位氨基酸是精氨酸或天冬氨酸已有不同的报道。我们发现,122位的1.2区缺失和单一氨基酸替换的行为都受到氨基酸149的同一性的很大影响。
The identity of amino acid 149 ofEscherichia coliσ70has been reported variably as either arginine or aspartic acid. We show that the behavior of both a region 1.2 deletion and a single-amino-acid substitution at position 122 are greatly affected by the identity of amino acid 149.
