Two “Wild-Type” Variants of Escherichia coli σ 70 : Context-Dependent Effects of the Identity of Amino Acid 149

Year: 2002

Type: article

Abstract: The identity of amino acid 149 of Escherichia coli sigma(70) has 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.
