VARIANT RNA POLYMERASE

摘要

PROBLEM TO BE SOLVED: To provide an improved T7RNA polymerase which increases the specific activity of bacteriophage T7RNA polymerase to improve reactivity in a high temperature range.

SOLUTION: Provided is a variant T7RNA polymerase obtained by replacing a tryptophan residue corresponding to the 344-position of the amino acid sequence of a wild T7RNA polymerase derived from bacteriophage T7 by valine residue.
