title: Virus-induced proteins in pseudorabies-infected cells. I. Acid-extractable proteins of the nucleus.
abstract: Three basic proteins have been identified in chromatin preparations from pseudorabies virus-infected cells. They appear to be virus specified and are similar in size and charge to host histones; one difference however is that they contain tryptophan. All are produced by 3 h postinfection, and two (IP II and III) seem to be arginine rich. Three similar proteins are also found in herpes simplex MP 17-infected cells, and two of these co-electrophorese with two of the pseudorabies proteins. Partially purified preparations of pseudorabies virus contain low amounts of all three proteins.
