Figure 1

A schematic diagram of the GLRaV-3 genome. The ORFs, numbered as 1 to 12 above the diagram, are shown as boxes with associated protein designations. L-Pro, leader proteinase; AlkB, AlkB domain; MET, HEL, and POL, methyltransferase, RNA helicase, and RNA-dependent RNA polymerase domains of the replicase, respectively; p6, a 6-kDa protein; p5, a 5-kDa protein; HSP70 h, a HSP70-homologue; p55, a 55-kDa protein; CP, the major capsid protein; CPm, the minor capsid protein; and p21, p20A, p20B, p4 and p7 are the 21-, 19.6-, 19.7-, 4- and 7-kDa proteins, respectively. Below the genome map is a representation of (right) the 11 putative subgenomic messenger (m) RNAs for the 3' genes and (left) the polyproteins from ORFs 1a and 1b. The subgenomic mRNAs and their transcription start sites identified in this study are shown with an asterisk. Arrow head indicates site of +1 ribosomal frameshift.
