COMMENTARY 
LITERATURE
G149D
-
site-directed mutagenesis, the mutant is deficient in both nucleotide incision repair and exonuclease activities
H69A
-
site-directed mutagenesis, the mutant is deficient in both nucleotide incision repair and exonuclease activities. The crystal structure of Nfo-H69A mutant reveals the loss of one of the active site zinc atoms and rearrangements of the catalytic site, but no gross changes in the overall enzyme conformation

Tequatrovirus T4
-
mutant enzyme retains cleavage activity (17.5% of that of wild-type Endo IV), but loses the polarized and restricted cleavage of a dCs tract. Escherichia coli cells expressing the intact Endo IV mutant enzyme are viable and, in contrast to wild-type Endo IV, the mutant enzyme does not show detrimental effect on the host cells
W88R
Tequatrovirus T4
-
mutant enzyme shows no enzymatic activity (less than 0.4% of that of wild-type Endo IV). Escherichia coli cells expressing the intact Endo IV mutant enzyme are viable and, in contrast to wild-type Endo IV, these mutant enzymes do not show detrimental effect on the host cells
