Glycosyl-hydrolase family 116, catalytic region. This represents a family of archaeal, bacterial and eukaryotic glycosyl hydrolases, that belong to superfamily GH116. The primary catabolic pathway for glucosylceramide is catalysis by the lysosomal enzyme glucocerebrosidase. In higher eukaryotes, glucosylceramide is the precursor of glycosphingolipids, a complex group of ubiquitous membrane lipids. Mutations in the human protein cause motor-neurone defects in hereditary spastic paraplegia. The catalytic nucleophile, identified in UniProtKB:Q97YG8_SULSO, is a glutamine-335, with the likely acid/base at Asp-442 and the aspartates at Asp-406 and Asp-458 residues also playing a role in the catalysis of glucosides and xylosides that are beta-bound to hydrophobic groups. The family is defined as GH116, which presently includes enzymes with beta-glucosidase, EC:3.2.1.21, beta-xylosidase, EC:3.2.1.37, and glucocerebrosidase EC:3.2.1.45 activity.

beta-glucosidase 2, glycosyl-hydrolase family 116 N-term. This domain is found in bacteria, archaea and eukaryotes. This domain is typically between 320 to 354 amino acids in length. This domain is found associated with pfam04685. It is found just after the extreme N-terminus. The N-terminal is thought to be the luminal domain while the C terminal is the cytosolic domain. The catalytic domain of GBA-2 is unknown. The primary catabolic pathway for glucosylceramide is catalysis by the lysosomal enzyme glucocerebrosidase. In higher eukaryotes, glucosylceramide is the precursor of glycosphingolipids, a complex group of ubiquitous membrane lipids. Mutations in the human protein cause motor-neurone defects in hereditary spastic paraplegia. The catalytic nucleophile, identified in UniProtKB:Q97YG8_SULSO, is a glutamine-335 in the downstream family pfam04685.

Uncharacterized protein, contains GBA2_N and DUF608 domains [Function unknown].
