Protein

Endoglucanase-4

Gene

cel61a

Organism
Hypocrea jecorina (Trichoderma reesei)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Has endoglucanase activity on substrates containing beta-1,4 glycosidic bonds, like in carboxymethylcellulose (CMC), hydroxyethylcellulose (HEC) and beta-glucan. May be involved in the degradation of complex natural cellulosic substrates.1 Publication
