Description

Glycoside hydrolase family 3
GH3
comprises enzymes with a number of known activities; beta-glucosidase (
3.2.1.21
); beta-xylosidase (
3.2.1.37
); N-acetyl beta-glucosaminidase (
3.2.1.52
); glucan beta-1,3-glucosidase (
3.2.1.58
); cellodextrinase(
3.2.1.74
); exo-1,3-1,4-glucanase (
3.2.1
).

These enzymes are two-domain globular proteins that are N-glycosylated at three sites
[1]
. This entry represents the C-terminal domain superfamily, involved in catalysis and may be involved in binding beta-glucan
[1]
. Its structure has a flavodoxin-like fold, which consists of three layers (α/β/α) with parallel β-sheet of five strand.
