Two "wild-type" variants of Escherichia coli sigma(70): context-dependent effects of the identity of amino acid 149.

Journal of bacteriology - 1 Feb 2002

Baldwin Nicole E, McCracken Andrea, Dombroski Alicia J

Abstract excerpt

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.
