HBV Mutation Detail Information

Virus Mutation HBV Mutation M204V


Basic Characteristics of Mutations
Mutation Site M204V
Mutation Site Sentence Molecular modeling studies of adefovir diphosphate with the wild type and the mutant HBV polymerase-DNA complex demonstrated that the increase in adefovir sensitivity toward HBV polymerase mutants (rtL180M, rtM204V/I, rtL180M-M204V/I) is a result of increased van der Waals interaction and is supplemented by the decreased affinity of natural substrate toward the mutant HBV polymerase.

Abstract Molecular modeling studies of adefovir diphosphate with the wild type and the mutant HBV polymerase-DNA complex demonstrated that the increase in adefovir sensitivity toward HBV polymerase mutants (rtL180M, rtM204V/I, rtL180M-M204V/I) is a result of increased van der Waals interaction and is supplemented by the decreased affinity of natural substrate toward the mutant HBV polymerase. In the case of rtN236T mutant, loss of two hydrogen bonds accompanied by significant decrease in electrostatic interactions is observed, which explains the observed decrease in drug sensitivity and binding affinity of adefovir diphosphate toward the rtN236T mutant HBV polymerase.

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.
  • Immune: The article focuses on the study of mutations and immune.
  • Target Gene: Host genes that viral mutations may affect.
Clinical and Epidemiological Correlations
