Cdd ID	Domain	E-Value	qStart	qEnd	sStart	sEnd	Domain Description
cd10792	GH57N_AmyC_like	0.0	5	417	1	412	N-terminal catalytic domain of alpha-amylase ( AmyC ) and similar proteins. Alpha-amylases (alpha-1,4-glucan-4-glucanohydrolases, EC 3.2.1.1) play essential roles in alpha-glucan metabolism by catalyzing the hydrolysis of polysaccharides such as amylose starch, and beta-limit dextrin. This subfamily is represented by a novel alpha-amylase (AmyC) encoded by hyperthermophilic organism Thermotoga maritime ORF tm1438, and its prokaryotic homologs. AmyC functions as a homotetramer and shows thermostable amylolytic activity. It is strongly inhibited by acarbose. AmyC is composed of a N-terminal catalytic domain, containing a distorted TIM-barrel structure with a characteristic (beta/alpha)7 fold motif, and two additional less conserved domains. There are other two canonical alpha-amylases encoded from T. maritime that lack the sequence similarity to AmyC, and belong to a different superfamily.
COG1543	COG1543	0.0	3	559	1	502	Predicted glycosyl hydrolase, contains GH57 and DUF1957 domains [Carbohydrate transport and metabolism].
cd10816	GH57N_BE_TK1436_like	1.38e-113	5	417	1	423	N-terminal catalytic domain of Gh57 branching enzyme TK 1436 and similar proteins. The subfamily is represented by a novel branching-enzyme TK1436 of hyperthermophilic archaeon Thermococcus kodakaraensis KOD1. Branching enzymes (BEs, EC 2.4.1.18) play a key role in synthesis of alpha-glucans and they generally are classified into glycoside hydrolase family 13 (GH13). However, TK1436 belongs to the GH57 family. It functions as a monomer and possesses BE activity. TK1436 is composed of a distorted N-terminal (beta/alpha)7-barrel domain and a C-terminal five alpha-helical domain, both of which participate in the formation of the active-site cleft.
cd01022	GH57N_like	2.74e-64	8	417	1	313	N-terminal catalytic domain of heat stable retaining glycoside hydrolase family 57. Glycoside hydrolase family 57(GH57) is a chiefly prokaryotic family with the majority of thermostable enzymes coming from extremophiles (many of these 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. GH57s cleave alpha-glycosidic bonds by employing a retaining mechanism, which involves a glycosyl-enzyme intermediate, allowing transglycosylation.
pfam09210	DUF1957	7.31e-47	468	558	7	98	Domain of unknown function (DUF1957). This domain is found in a set of hypothetical bacterial proteins. Its exact function has not, as yet, been defined.
