Fine structure mapping of five temperature-sensitive mutants in the 22- and 147-kilodalton subunits of vaccinia virus DNA-dependent RNA polymerase.

abstract：:The ability of human immunodeficiency virus type 1 (HIV-1) to transduce nondividing cells is key to infecting terminally differentiated macrophages, which can serve as a long-term reservoir of HIV-1 infection. The mutation N57A in the viral CA protein renders HIV-1 cell cycle dependent, allowing examination of HIV-1 i...
