"We have studied expression of the catalytic subunit of a phosphonoacetic acid-resistant (PAA(r)) DNA polymerase (Pol) of herpes simplex virus type 1 (HSV-1) strain ANG by recombinant vaccinia virus (VV) engineered with the dominant Ecogpt selection system. In agreement with the vector construction recombinant Pol expression was regulated like a VV late function," investigators in Cologne, Germany report. "De novo-synthesis of the 136-kDa Pol polypeptide was detectable as early as 6 h postinfection, peaked between 10 and 12 h, and correlated with specific polymerase activity. Compared with HSV-1 lytic infection, the recombinant Pol protein exhibited a reduced stability...
