A potent insect chitinase inhibitor of fungal origin.

چکیده
A water-soluble polysaccharide was isolated from the culture filtrate of a fungal strain, Sphaeropsis sp. TNPT116-Cz, as a novel insect chitinase inhibitor. It was purified to chromatographic homogeneity by ethanol precipitation, anion-exchange and gel filtration chromatography. Its molecular weight was estimated to be 16 kDa by gel filtration HPLC. Monosaccharide analysis showed that it contained glucose, galactose, N-acetylglucosamine and a deoxysugar. This polysaccharide showed potent and specific inhibitory activity against Spodoptera litura chitinase with an IC50 value of 28 nM.

Purification and characterisation of a 31-kDa chitinase from the Myzus Persicae aphid: a target for hemiptera biocontrol.
Hydrolytic enzymes involved in chitin degradation are important to allow moulting during insect development. Chitinases are interesting targets to disturb growth and develop alternative strategies to control insect pests. In this work, a chitinase from the aphid Myzus persicae was purified with a 36-fold purification rate in a three step procedure by ammonium sulphate fractionation, anion-excha...
متن کاملIdentification and expression analyses of chitinase genes in mulberry (Morus L) plants
In the present study, we identified chitinase genes in the genome of mulberry for the first time. The mulberry genome encodes 20 chitinase genes, which are grouped into two main families and organized into five classes. The genomic structures and phylogenetic relationships of mulberry chitinase genes were analyzed, which provided a genetic basis for understanding the functions of these genes. W...
متن کاملIncreased insect virulence in Beauveria bassiana strains overexpressing an engineered chitinase.
Entomopathogenic fungi are currently being used for the control of several insect pests as alternatives or supplements to chemical insecticides. Improvements in virulence and speed of kill can be achieved by understanding the mechanisms of fungal pathogenesis and genetically modifying targeted genes, thus improving the commercial efficacy of these biocontrol agents. Entomopathogenic fungi, such...
متن کاملErratum: Development of insect resistant maize plants expressing a chitinase gene from the cotton leaf worm, Spodoptera littoralis
Due to the importance of chitinolytic enzymes for insect, nematode and fungal growth, they are receiving attention concerning their development as biopesticides or chemical defense proteins in transgenic plants and as microbial biocontrol agents. Targeting chitin associated with the extracellular matrices or cell wall by insect chitinases may be an effective approach for controlling pest insect...
متن کاملMethylxanthine drugs are chitinase inhibitors: investigation of inhibition and binding modes.
Family 18 chitinases play key roles in a range of pathogenic organisms and are overexpressed in the asthmatic lung. By screening a library of marketed drug molecules, we have identified methylxanthine derivatives as possible inhibitor leads. These derivatives, theophylline, caffeine, and pentoxifylline, are used therapeutically as antiinflammatory agents, with pleiotropic mechanisms of action. ...
