cd09019 galactose_mutarotase_like 3.30e-161 351 686 1 326
galactose mutarotase_like. Galactose mutarotase catalyzes the conversion of beta-D-galactose to alpha-D-galactose. Beta-D-galactose is produced by the degradation of lactose, a disaccharide composed of beta-D-glucose and beta-D-galactose. This epimerization reaction is the first step in the four-step Leloir pathway, which converts galactose into metabolically important glucose. This epimerization step is followed by the phosophorylation of alpha-D-galactose by galactokinase, an enzyme which can only act on the alpha anomer. A glutamate and a histidine residue of the galactose mutarotase have been shown to be critical for catalysis, the glutamate serves as the active site base to initiate the reaction by removing the proton from the C-1 hydroxyl group of the sugar substrate, and the histidine as the active site acid to protonate the C-5 ring oxygen. Galactose mutarotase is a member of the aldose-1-epimerase superfamily.
cd18616 GH43_ABN-like 7.88e-144 26 303 1 291
Glycosyl hydrolase family 43 such as arabinan endo-1 5-alpha-L-arabinosidase. This glycosyl hydrolase family 43 (GH43) subgroup includes mostly enzymes with endo-alpha-L-arabinanase (ABN; EC 3.2.1.99) activity. These are inverting enzymes (i.e. they invert the stereochemistry of the anomeric carbon atom of the substrate) that have an aspartate as the catalytic general base, a glutamate as the catalytic general acid and another aspartate that is responsible for pKa modulation and orienting the catalytic acid. The GH43 ABN enzymes hydrolyze alpha-1,5-L-arabinofuranoside linkages. These arabinan-degrading enzymes are important in the food industry for efficient production of L-arabinose from agricultural waste; L-arabinose is often used as a bioactive sweetener. A common structural feature of GH43 enzymes is a 5-bladed beta-propeller domain that contains the catalytic acid and catalytic base. A long V-shaped groove, partially enclosed at one end, forms a single extended substrate-binding surface across the face of the propeller.
TIGR02636 galM_Leloir 1.82e-108 346 687 1 336
galactose mutarotase. Members of this protein family act as galactose mutarotase (D-galactose 1-epimerase) and participate in the Leloir pathway for galactose/glucose interconversion. All members of the seed alignment for this model are found in gene clusters with other enzymes of the Leloir pathway. This enzyme family belongs to the aldose 1-epimerase family, described by pfam01263. However, the enzyme described as aldose 1-epimerase itself (EC 5.1.3.3) is called broadly specific for D-glucose, L-arabinose, D-xylose, D-galactose, maltose and lactose. The restricted genome context for genes in this family suggests members should act primarily on D-galactose.
