title: Promoting protein, a silkworm hemolymph protein promoting in vitro replication of nucleopolyhedrovirus, binds to beta-glucans.
abstract: A protein which bound to 125I-labeled peptidoglycan (PGN) was isolated from hemolymph of silkworm larvae. The N-terminal amino acid sequence and the molecular weight of the protein were in accord with those described for Promoting Protein (PP) from the silkworm. The binding of the protein to [125I]PGN was competitively inhibited by various beta-glucans. The binding kinetics of PGN and chitin to the protein were analyzed in a biosensor.
