Organism

Aspergillus kawachii (strain NBRC 4308) (White koji mold) (Aspergillus awamori var. kawachi) [Complete proteome]

Taxonomic identifier

1033177 [NCBI]

Taxonomic lineage

cellular organisms › Eukaryota › Opisthokonta › Fungi › Dikarya › Ascomycota › saccharomyceta › Pezizomycotina › leotiomyceta › Eurotiomycetes › Eurotiomycetidae › Eurotiales › Trichocomaceae › mitosporic Trichocomaceae › Aspergillus › Aspergillus kawachii

Protein attributes

Sequence length	408 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Has endoglucanase activity on substrates containing beta-1,4 glycosidic bonds, like in carboxymethylcellulose (CMC), hydroxyethylcellulose (HEC) and beta-glucan. Involved in the degradation of complex natural cellulosic substrates By similarity.
Catalytic activity	Endohydrolysis of (1->4)-beta-D-glucosidic linkages in cellulose, lichenin and cereal beta-D-glucans.
Subcellular location	Secreted By similarity.
Domain	Has a modular structure: an endo-beta-1,4-glucanase catalytic module at the N-terminus, a linker rich in serines and threonines, and a C-terminal carbohydrate-binding module (CBM). The genes for catalytic modules and CBMs seem to have evolved separately and have been linked by gene fusion.
Sequence similarities	Belongs to the glycosyl hydrolase 61 family. Contains 1 CBM1 (fungal-type carbohydrate-binding) domain.
