Figure 8

Amino acid change analysis of enterovirus D68, subgenotype A2, from report on national surveillance of enterovirus D68 upsurge, France, 2021–2024. Amino acid substitutions leading to changes in the predominant residues between the newly identified A2-II group (n = 50 sequences) and the previously circulating A2-I (n = 75 sequences) clade are shown. Mutation positions are numbered according to the reference Fermon strain (GenBank accession no. AY426531) and annotated by the corresponding viral proteins (structural proteins VP2, VP3, and VP1 and nonstructural proteins 2A, 2C, 3A, and 3D). A, alanine; D, aspartate; E, glutamate; G, glycine; H, histidine; I, isoleucine; K, lysine; M, methionine; N, asparagine; R, arginine; S, serine; T, threonine; V, valine; VP, viral protein; Y, tyrosine.
