cd10791	GH38N_AMII_like_1	3.13e-73	7	267	1	253	N-terminal catalytic domain of mainly uncharacterized eukaryotic proteins similar to alpha-mannosidases; glycoside hydrolase family 38 (GH38). The subfamily of mainly uncharacterized eukaryotic proteins shows sequence homology with class II alpha-mannosidases (AlphaAMIIs). AlphaAMIIs possess a-1,3, a-1,6, and a-1,2 hydrolytic activity, and catalyze the degradation of N-linked oligosaccharides. The N-terminal catalytic domain of alphaMII adopts a structure consisting of parallel 7-stranded beta/alpha barrel. This subfamily belongs to the GH38 family of retaining glycosyl hydrolases, which employ a two-step mechanism involving the formation of a covalent glycosyl enzyme complex; two carboxylic acids positioned within the active site act in concert: one as a catalytic nucleophile and the other as a general acid/base catalyst.

cd10786	GH38N_AMII_like	9.97e-05	7	192	1	186	N-terminal catalytic domain of class II alpha-mannosidases and similar proteins; glycoside hydrolase family 38 (GH38). Alpha-mannosidases (EC 3.2.1.24) are extensively found in eukaryotes and play important roles in the processing of newly formed N-glycans and in degradation of mature glycoproteins. A deficiency of this enzyme causes the lysosomal storage disease alpha-mannosidosis. Many bacterial and archaeal species also possess putative alpha-mannosidases, but their activity and specificity is largely unknown. Based on different functional characteristics and sequence homology, alpha-mannosidases have been organized into two classes (class I, belonging to glycoside hydrolase family 47, and class II, belonging to glycoside hydrolase family 38). Members of this family corresponds to class II alpha-mannosidases (alphaMII), which contain intermediate Golgi alpha-mannosidases II, acidic lysosomal alpha-mannosidases, animal sperm and epididymal alpha -mannosidases, neutral ER/cytosolic alpha-mannosidases, and some putative prokaryotic alpha-mannosidases. AlphaMII possess a-1,3, a-1,6, and a-1,2 hydrolytic activity, and catalyzes the degradation of N-linked oligosaccharides. The N-terminal catalytic domain of alphaMII adopts a structure consisting of parallel 7-stranded beta/alpha barrel. Members in this family are retaining glycosyl hydrolases of family GH38 that employs a two-step mechanism involving the formation of a covalent glycosyl enzyme complex. Two carboxylic acids positioned within the active site act in concert: one as a catalytic nucleophile and the other as a general acid/base catalyst.
cd00451	GH38N_AMII_euk	0.002	6	84	1	78	N-terminal catalytic domain of eukaryotic class II alpha-mannosidases; glycoside hydrolase family 38 (GH38). The family corresponds to a group of eukaryotic class II alpha-mannosidases (AlphaMII), which contain Golgi alpha-mannosidases II (GMII), the major broad specificity lysosomal alpha-mannosidases (LAM, MAN2B1), the noval core-specific lysosomal alpha 1,6-mannosidases (Epman, MAN2B2), and similar proteins. GMII catalyzes the hydrolysis of the terminal both alpha-1,3-linked and alpha-1,6-linked mannoses from the high-mannose oligosaccharide GlcNAc(Man)5(GlcNAc)2 to yield GlcNAc(Man)3(GlcNAc)2 (GlcNAc, N-acetylglucosmine), which is the committed step of complex N-glycan synthesis. LAM is a broad specificity exoglycosidase hydrolyzing all known alpha 1,2-, alpha 1,3-, and alpha 1,6-mannosidic linkages from numerous high mannose type oligosaccharides. Different from LAM, Epman can efficiently cleave only the alpha 1,6-linked mannose residue from (Man)3GlcNAc, but not (Man)3(GlcNAc)2 or other larger high mannose oligosaccharides, in the core of N-linked glycans. Members in this family are retaining glycosyl hydrolases of family GH38 that employs a two-step mechanism involving the formation of a covalent glycosyl enzyme complex. Two carboxylic acids positioned within the active site act in concert: one as a catalytic nucleophile and the other as a general acid/base catalyst.
cd10809	GH38N_AMII_GMII_SfManIII_like	0.002	8	84	4	79	N-terminal catalytic domain of Golgi alpha-mannosidase II, Spodoptera frugiperda Sf9 alpha-mannosidase III, and similar proteins; glycoside hydrolase family 38 (GH38). This subfamily is represented by Golgi alpha-mannosidase II (GMII, also known as mannosyl-oligosaccharide 1,3- 1,6-alpha mannosidase, EC 3.2.1.114, Man2A1), a monomeric, membrane-anchored class II alpha-mannosidase existing in the Golgi apparatus of eukaryotes. GMII plays a key role in the N-glycosylation pathway. It catalyzes the hydrolysis of the terminal both alpha-1,3-linked and alpha-1,6-linked mannoses from the high-mannose oligosaccharide GlcNAc(Man)5(GlcNAc)2 to yield GlcNAc(Man)3(GlcNAc)2(GlcNAc, N-acetylglucosmine), which is the committed step of complex N-glycan synthesis. GMII is activated by zinc or cobalt ions and is strongly inhibited by swainsonine. Inhibition of GMII provides a route to block cancer-induced changes in cell surface oligosaccharide structures. GMII has a pH optimum of 5.5-6.0, which is intermediate between those of acidic (lysosomal alpha-mannosidase) and neutral (ER/cytosolic alpha-mannosidase) enzymes. GMII is a retaining glycosyl hydrolase of family GH38 that employs a two-step mechanism involving the formation of a covalent glycosyl enzyme complex; two carboxylic acids positioned within the active site act in concert: one as a catalytic nucleophile and the other as a general acid/base catalyst. This subfamily also includes human alpha-mannosidase 2x (MX, also known as mannosyl-oligosaccharide 1,3- 1,6-alpha mannosidase, EC 3.2.1.114, Man2A2). MX is enzymatically and functionally very similar to GMII, and is thought to also function in the N-glycosylation pathway. Also found in this subfamily is class II alpha-mannosidase encoded by Spodoptera frugiperda Sf9 cell. This alpha-mannosidase is an integral membrane glycoprotein localized in the Golgi apparatus. It shows high sequence homology with mammalian Golgi alpha-mannosidase II(GMII). It can hydrolyze p-nitrophenyl alpha-D-mannopyranoside (pNP-alpha-Man), and it is inhibited by swainsonine. However, the Sf9 enzyme is stimulated by cobalt and can hydrolyze (Man)5(GlcNAc)2 to (Man)3(GlcNAc)2, but it cannot hydrolyze GlcNAc(Man)5(GlcNAc)2, which is distinct from that of GMII. Thus, this enzyme has been designated as Sf9 alpha-mannosidase III (SfManIII). It probably functions in an alternate N-glycan processing pathway in Sf9 cells.
