Abstract
An ORF having a potential to code for a polypeptide of 79 amino acids has been identified within 993 nt sequence of 2 kb EcoRI-W fragment of Spodoptera litura nucleopolyhedrovirus (SpltNPV-I). Nucleotide and deduced amino acid sequence analyses showed its identity with the ubiquitin homologue of eukaryotes (79–80%), Melanoplus sanguinipes entomopoxvirus (76%) and other baculoviruses (72–89%). The ORF is under baculovirus late promoter motif RTAAG but unlike other baculoviruses, three such motifs at −6, −10 and −27 position are present in SpltNPV. The ORF expresses as a 10 kDa protein in E. coli and the purified recombinant protein showed crossreactivity with the rabbit anti-ubiquitin antibodies.
