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.
