Residue 752 in DNA polymerase of equine herpesvirus type 1 is non-essential for virus growth in vitro

A single amino acid variation in the equine herpesvirus type 1 (EHV-1) DNA polymerase (Pol) (D752/N752) determines its neuropathogenic potential. Here, an EHV-1 strain RacL11 mutant with a deletion of Pol residue 752 was constructed. The deletion virus was then repaired to encode D752 or N752, respe...
