Schematic representation of the LIYV genome. Rectangles represent ORFs. P-PRO, papain-like protease; MTR, methyltransferase; HEL, RNA helicase; RDRP, RNA-dependent RNA polymerase; HSP70, homologue of HSP70 proteins; CP, capsid protein; and CPm, diverged duplicate of the capsid protein (minor capsid protein). Proteins of unknown function are indicated by their respective molecular weight × 10-3 (i.e. P32 = a protein of unknown function of Mr 32,000).
