Unique Temperature-Sensitive Defect in Vaccinia Virus Morphogenesis Maps to a Single Nucleotide Substitution in the A30L Gene

Received 2 July 2001/Accepted 9 August 2001

Marker rescue experiments demonstrated that the genetic lesion of a previously isolated vaccinia virus temperature-sensitive mutant which forms multilayered envelope structures with lucent interiors and foci of viroplasm with dense centers mapped to the A30L open reading frame. A single base change, resulting in a nonconservative Ser-to-Phe substitution at residue 17, was associated with degradation of the A30L protein at elevated temperatures.
