Endochitinase A1

Gene

chiA1

Organism
Neosartorya fumigata (strain ATCC MYA-4609 / Af293 / CBS 101355 / FGSC A1100) (Aspergillus fumigatus)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Protein inferred from homologyi

Functioni

GPI-anchored 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). Required to reshape the cell wall at the sites where cell wall remodeling and/or cell wall maturation actively take place such as sites of conidia formation (By similarity).By similarity

Catalytic activityi

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

Enzyme regulationi

The cyclic peptide natural product argifin acts as a specific inhibitor.By similarity
