Protein

Endochitinase 46

Gene

chit46

Organism
Trichoderma harzianum (Hypocrea lixii)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Secreted chitinase involved in the degradation of chitin, a component of the cell walls of fungi and exoskeletal elements of some animals (including worms and arthropods). Plays a morphogenetic role during apical growth, cell division and differentiation (cell wall morphogenesis). Acts also as an antifungal agent. Involved in the degradation and further assimilation of phytopathogenic fungi, namely mycoparasitism, the major mechanism accounting for the antagonistic activity against phytopathogenic fungi displayed by Trichoderma.1 Publication

Catalytic activityi

Random endo-hydrolysis of N-acetyl-beta-D-glucosaminide (1->4)-beta-linkages in chitin and chitodextrins.
