| cd06568 | GH20_SpHex_like | 2.07e-157 | 182 | 554 | 1 | 329 | A subgroup of the Glycosyl hydrolase family 20 (GH20) catalytic domain found in proteins similar to the N-acetylhexosaminidase from Streptomyces plicatus (SpHex). SpHex catalyzes the hydrolysis of N-acetyl-beta-hexosaminides. An Asp residue within the active site plays a critical role in substrate-assisted catalysis by orienting the 2-acetamido group and stabilizing the transition state. The GH20 hexosaminidases are thought to act via a catalytic mechanism in which the catalytic nucleophile is not provided by solvent or the enzyme, but by the substrate itself. Proteins belonging to this subgroup lack the C-terminal PKD (polycystic kidney disease I)-like domain found in the chitobiases. |
| cd06563 | GH20_chitobiase-like | 2.25e-109 | 182 | 554 | 1 | 357 | The chitobiase of Serratia marcescens is a beta-N-1,4-acetylhexosaminidase with a glycosyl hydrolase family 20 (GH20) domain that hydrolyzes the beta-1,4-glycosidic linkages in oligomers derived from chitin. Chitin is degraded by a two step process: i) a chitinase hydrolyzes the chitin to oligosaccharides and disaccharides such as di-N-acetyl-D-glucosamine and chitobiose, ii) chitobiase then further degrades these oligomers into monomers. This GH20 domain family includes an N-acetylglucosamidase (GlcNAcase A) from Pseudoalteromonas piscicida and an N-acetylhexosaminidase (SpHex) from Streptomyces plicatus. SpHex lacks the C-terminal PKD (polycystic kidney disease I)-like domain found in the chitobiases. The GH20 hexosaminidases are thought to act via a catalytic mechanism in which the catalytic nucleophile is not provided by solvent or the enzyme, but by the substrate itself. |

| cd02742 | GH20_hexosaminidase | 6.40e-76 | 184 | 540 | 1 | 303 | Beta-N-acetylhexosaminidases of glycosyl hydrolase family 20 (GH20) catalyze the removal of beta-1,4-linked N-acetyl-D-hexosamine residues from the non-reducing ends of N-acetyl-beta-D-hexosaminides including N-acetylglucosides and N-acetylgalactosides. These enzymes are broadly distributed in microorganisms, plants and animals, and play roles in various key physiological and pathological processes. These processes include cell structural integrity, energy storage, cellular signaling, fertilization, pathogen defense, viral penetration, the development of carcinomas, inflammatory events and lysosomal storage disorders. The GH20 enzymes include the eukaryotic beta-N-acetylhexosaminidases A and B, the bacterial chitobiases, dispersin B, and lacto-N-biosidase. The GH20 hexosaminidases are thought to act via a catalytic mechanism in which the catalytic nucleophile is not provided by the solvent or the enzyme, but by the substrate itself. |
