The partial protein kinase gene of Spodoptera litura nuclear polyhedrosis virus was sequenced. The predicted Sl NPV protein kinase shows 45%

44%

89%

37%

38% and 37% amino acid homology to those of Ha NPV

Hz NPV

Spli NPV

Af NPV

Ac MNPV and Ld NPV

respectively. There is an IVHANDVKLENVL pattern in the protein kinase of Sl NPV

which is the signature motif of protein kinase family.
