Accepted name: chitinase

Reaction: Random hydrolysis of N-acetyl-β-D-glucosaminide (1→4)-β-linkages in chitin and chitodextrins

Other name(s): chitodextrinase; 1,4-β-poly-N-acetylglucosaminidase; poly-β-glucosaminidase; β-1,4-poly-N-acetyl glucosamidinase; poly[1,4-(N-acetyl-β-D-glucosaminide)] glycanohydrolase

Systematic name: (1→4)-2-acetamido-2-deoxy-β-D-glucan glycanohydrolase

Comments: Some chitinases also display the activity defined in EC lysozyme.
