Enterococcus faecalis EF3048 and similar proteins; This subfamily is represented by a putative cellobiose-phosphate cleavage protein EF3048 from Enterococcus faecalis v583. It is similar to Escherichia coli YdjC, a hypothetical protein encoded by the celG gene. EF3048 might function as a homodimer. Each of the monomers consists of a (beta/alpha)-barrel fold that forms an active homodimer. The molecular function of the EF3048 is unclear.

YdjC-family proteins; YdjC-family proteins are widely distributed, from human to bacteria. It is represented by an uncharacterised protein YdjC (also known as ChbG), encoded by the chb (N,N'-diacetylchitobiose, also called [GlcNAc]2) or cel operon in Escherichia coli, which encodes enzymes involved in growth on an N,N'-diacetylchitobiose carbon source. This subfamily also includes hopanoid biosynthesis associated proteins HpnK and many uncharacterized YdjC homologs. Although the exact molecular function of the YdjC-family proteins remains unclear, it has been suggested that they play a role in the cleavage of cellobiosephosphate.

Catalytic domain of glycoside hydrolase (GH) families 38 and 57, lactam utilization protein LamB/YcsF family proteins, YdjC-family proteins, and similar proteins; The superfamily possesses strong sequence similarities across a wide range of all three kingdoms of life. It mainly includes four families, glycoside hydrolases family 38 (GH38), heat stable retaining glycoside hydrolases family 57 (GH57), lactam utilization protein LamB/YcsF family, and YdjC-family. The GH38 family corresponds to class II alpha-mannosidases (alphaMII, EC 3.2.1.24), 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 by employing a two-step mechanism involving the formation of a covalent glycosyl enzyme complex. GH57 is a purely prokaryotic family with the majority of thermostable enzymes from extremophiles (many of them are archaeal hyperthermophiles), which exhibit the enzyme specificities of alpha-amylase (EC 3.2.1.1), 4-alpha-glucanotransferase (EC 2.4.1.25), amylopullulanase (EC 3.2.1.1/41), and alpha-galactosidase (EC 3.2.1.22). This family also includes many hypothetical proteins with uncharacterized activity and specificity. GH57 cleaves alpha-glycosidic bond by employing a retaining mechanism, which involves a glycosyl-enzyme intermediate, allowing transglycosylation. Although the exact molecular function of LamB/YcsF family and YdjC-family remains unclear, they show high sequence and structure homology to the members of GH38 and GH57. Their catalytic domains adopt a similar parallel 7-stranded beta/alpha barrel, which is remotely related to catalytic NodB homology domain of the carbohydrate esterase 4 superfamily.

(labeled illustration) Four types of hits can be shown, as available,
