Abstract By comparative sequence analysis of the herpes simplex virus type 1 DNA polymerase gene of strain Angelotti and a phosphonoacetic acid-resistant (PAAr) derivative, the site of the PAAr mutation was identified as a single nucleotide (C----T) conversion within the mapping limits of the known PAAr mutations of strains KOS and 17. The conservative amino acid change at residue 719 from alanine to valine results in a radical change in the properties of the polymerase, rendering the mutant enzyme resistant to PAA and various antiviral compounds. Amino acid homologies as well as secondary structure analysis reveal that the PAAr mutation is contained in a 14 amino acid sequence which is highly conserved, and detected in the central domain of prokaryotic and eukaryotic DNA polymerases.

Note
Basic Characteristics of Mutations
  • Mutation Site: The specific location in a gene or protein sequence where a change occurs.
  • Mutation Level: The level at which a mutation occurs, including the nucleotide or amino acid level.
  • Mutation Type: The nature of the mutation, such as missense mutation, nonsense mutation, synonymous mutation, etc.
  • Gene/Protein/Region: Refers to the specific region of the virus where the mutation occurs. Including viral genes, viral proteins, or a specific viral genome region. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main
  • Gene/Protein/Region studied in the article is marked.
  • Genotype/Subtype: Refers to the viral genotype or subtype where the mutation occurs. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main Genotype/Subtype studied in the article is marked.
  • Viral Reference: Refers to the standard virus strain used to compare and analyze viral sequences.
Functional Impact and Mechanisms
  • Disease: An abnormal physiological state with specific symptoms and signs caused by viral infection.
