Cloned(Commentary)

Cloned (Comment) Organism
expressed in Escherichia coli C41(DE3) cells Tequatrovirus T4

Protein Variants

Protein Variants Comment Organism
G14D the mutation impairs the 5`-kinase activity of the enzyme in vivo as well as in vitro and leads to diminished processing at secondary sites of several RegB-cleaved transcripts Tequatrovirus T4
R229H the mutant shows slightly reduced wild type activity Tequatrovirus T4
