RESEARCH ADVANCES ON STRUCTURES AND FUNCTIONS OF BACULOVIRUS CHITINASE GENES / 微生物学通报

ABSTRACT

The chitinase gene of baculovirus is an unnecessary and high conservative gene Chitinase is expressed in the late phase virus replication in insect cells There are signal peptide in its N termini, chitinases active motifs in its central section and ER attaching motifs of chitinase in its C termini Baculoviral chitinase possesses both endo and exo chitinase activities, which can hydrolyze inherent chitin in insects body Chitinase is necessary for liquefaction of the virus infected host insect, and it may also serve as a molecular chaperone for pro V Cath Perhaps Baculoviral chitinase has same ancestors with bacteriums chitinase
