Mutations affecting the high affinity ATPase center of gpA, the large subunit of bacteriophage lambda terminase, inactivate the endonuclease activity of terminase.

Abstract excerpt

Phage lambda terminase carries out the cos cleavage reaction that generates mature chromosomes from immature concatemeric DNA. The ATP-stimulated endonuclease activity of terminase is located in gpA, the large terminase subunit. There is a high affinity ATPase center in gpA, and a match to the co...
