General annotation (Comments)

Function

Hydrolyzes chitin and plays a role in defense against fungal pathogens containing chitin. Its overexpression confers enhanced resistance to sheath blight pathogen (R.solani). Ref.5

Catalytic activity

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

Tissue specificity

Expressed in meristems and at lower levels in roots and sheaths. Ref.6

Sequence similarities

Belongs to the glycosyl hydrolase 19 family. Chitinase class I subfamily.

Contains 1 chitin-binding type-1 domain.

Sequence caution

The sequence described in Ref.1 differs from that shown. Reason: Frameshift at several positions.

The sequence described in Ref.1 differs from that shown. Reason: Sequencing errors.
