Abstract

It is intended to provide an extract, kit and a process for synthesizing a protein in a cell-free system. The extract is characterized by being prepared from mutant Escherichia coli cells having a mutation in the ribosomal protein S12 gene. In a preferred embodiment, the mutation is such a mutation as conferring a resistance or dependence to streptomycin on E. coli whereby the reading efficiency of mRNA codon on ribosomes can be improved and thus the protein productivity can be elevated.
