Isolation and characterization of mutant bacteriophage T7 RNA polymerases.

Journal of molecular biology - 20 Mar 1992

Patra D, Lafer E M, Sousa R

Abstract excerpt

We have isolated and characterized a number of bacteriophage T7 RNAP (RNA polymerase) null mutants. Most of the mutants found to be completely inactive in vitro map to one of the well-conserved blocks of residues in the family of RNAPs homologous to T7 RNAP. The in vitro phenotypes of a smaller number of partially active T7 RNAP mutants, mapping outside these well-conserved regions, support the following...
