Subcellular location

Vacuole By similarity. Note: Vacuolar and protoplast By similarity. UniProtKB P19171

Sequence similarities

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

Mass spectrometry

Molecular mass is 26534 Da from positions 1 - 243. Determined by ESI. Ref.1
