Hantavirus NSs ORF. a) Schematic presentation of hantavirus S segment. TULV NSs protein is 90 aa and N protein 429 aa in length. b) NSs ORF sequences of TULV/Lodz and TULV/Moravia. TULV/Lodz codes for the full-length NSs protein of 90 aa. TULV/Moravia NSs ORF contains a stop codon at the place of Glu-15 and the production of truncated protein presumably begins from Met-24 or Met-25 (bold and underlined) and thus yields a protein of 66–67 aa in length. *, stop codon.
