EC 3.2.1.203     
Accepted name: carboxymethylcellulase
Reaction: Endohydrolysis of (1→4)-β-D-glucosidic linkages in (carboxymethyl)cellulose.
Other name(s): CMCase
Systematic name: 4-β-D-(carboxymethyl)glucan 4-(carboxymethyl)glucanohydrolase
Comments: The enzyme from the acidophilic bacterium Alicyclobacillus acidocaldarius is an endo-cleaving hydrolase that cleaves β(1→4)-linked residues. However, it is specific for (carboxymethyl)cellulose and does not act on cellulosic substrates such as avicel.
