Natural precipitating proteins in insect haemolymph
Journal of Insect Physiology, 1970Abstract Spontaneous precipitation of haemolymph proteins of Galleria mellonella and Periplaneta americana occurred when diffused in agar phosphate buffered at pH 7·4. Insect plasma protein of these two species diffused against each other in agar borate at pH 9·0 (a condition which minimized spontaneous or autoprecipitation), developed precipitated ...

Insect antibacterial proteins: Not just for insects and against bacteria
BioEssays, 1991AbstractIn response to a bacterial infection, insects launch an array of countermeasures. Among these are the antibacterial proteins, which effectively lyse bacteria or are bacteriostatic. These proteins were generally assumed to be restricted to insects, yet recent information has shown some homologous counterparts in verte brates, including humans ...

Insect chitinase and chitinase-like proteins
Cellular and Molecular Life Sciences, 2009Insect chitinases belong to family 18 glycosylhydrolases that hydrolyze chitin by an endo-type of cleavage while retaining the anomeric beta-(1-->4) configuration of products. There are multiple genes encoding chitinases and chitinase-like proteins in all insect species studied using bioinformatics searches.

Peptidoglycan recognition proteins in insect immunity
Molecular Immunology, 2019Insects lack an acquired immune system and rely solely on the innate immune system to combat microbial infection. The innate immunity of insects mainly depends on the interaction between the host's pattern recognition receptor (PRR) and pathogen-associated molecular pattern (PAMP).

Insect actomyosin ATPase—A regulatory protein
Archives of Biochemistry and Biophysics, 1967Abstract Substrate inhibition of insect actomyosin ATPase is overcome by Ca ++ . This activating effect and the binding of Ca ++ to the protein are cooperative. The Ca ++ -activated ATPase is under cooperative inhibition by ADP. In the presence of inhibitory levels of ADP the enzyme also exhibits cooperative effects with respect to the substrate ...

SEROLOGY OF INSECT PROTEINS: I. PRELIMINARY STUDIES ON THE PROTEINS OF INSECT CUTICLE
Canadian Journal of Zoology, 1962Precipitin tests on extracts of larval cuticle of the housefly (Musca domestica L.) showed the presence of several antigenic protein components, and variations in the protein composition of cuticle during larval development were also demonstrated. One antigenic component from third-instar larval cuticle possessed phenol–oxidase activity.

Recombinant Proteins Produced in Insect Cells
2009Both purified expressed proteins and virus-like particles generated in insect cells by recombinant baculoviruses are being explored as potential vaccines for seasonal and pandemic influenza. Clinical trials have suggested that recombinant hemagglutinin vaccines are well tolerated in healthy and elderly adults, that they induce a functional antibody ...
