EcoKI with an amino acid substitution in any one of seven DEAD-box motifs has impaired ATPase and endonuclease activities.

For type I restriction systems, recently determined nucleotide sequences predict conserved amino acids in the subunit that is essential for restriction but not modification (HsdR). The conserved sequences emphasize motifs characteristic of the DEAD-box family of proteins which comprises putative hel...
