The polyhedrin gene of Spodoptera litura nuclear polyhedrosis virus was identified With a coding sequence of 780 nucleotides

corresponding to a protein of 249 amino acid

the polyhedrin gene of Sl NPV is the longest polyhedrin gene known This gene codes for a putative protein with a relative molecular mass ( M r) of 29 236 and the predicted amino acid sequence shows high homology with the amino acid sequences of other NPVs
