Encodes presumably for at least four polypeptides: Movement protein (MP), capsid protein (CP), Protease (PR), and reverse transcriptase (RT). a 2'-deoxyribonucleoside 5'-triphosphate + DNA(n) = diphosphate + DNA(n+1) a 2'-deoxyribonucleoside 5'-triphosphate + DNA(n) = diphosphate + DNA(n+1) Belongs to the Petuviruses genome polyprotein family.
