title: Protein kinase associated with Newcastle disease virus.
abstract: Purified virions of Newcastle disease virus (NDV) were found to contain protein kinase activity which was, like other virion-associated kinases, stimulated by Mg2+, and totally independent of Ca2+ and cAMP. The kinase phosphorylated preferentially the P and NP polypeptides of NDV. Triton-KCl fractionation of the virions has shown that the protein kinase activity may be associated with glycoprotein-free subviral particles, but not with nucleocapsids containing either only NP or some L and P proteins together with NP as protein constituent.
