Inhibition of vaccinia virus growth by zinc ions: effects on early RNA and thymidine kinase synthesis. 1979

V Zaslavsky

Accumulation of thymidine kinase activity in vaccinia virus-infected cells was severely inhibited by zinc ions if the drug was added within 1 h postinfection. If added later, zinc ions had no effect on the enzyme synthesis. A fraction of RNA which is normally synthesized in infected cells, was missing from a proper part of the gradient if the cells were treated with zinc ions within 1 h postinfection (as has been shown by cosedimentation of pulse-labeled RNAs in isokinetic gradients). It is suggested that a transcriptional (or posttranscriptional) step is involved in zinc-caused inhibition of vaccinia virus growth.

D015032	Zinc	A metallic element of atomic number 30 and atomic weight 65.38. It is a necessary trace element in the diet, forming an essential part of many enzymes, and playing an important role in protein synthesis and in cell division. Zinc deficiency is associated with ANEMIA, short stature, HYPOGONADISM, impaired WOUND HEALING, and geophagia. It is known by the symbol Zn.
