evolution
the enzyme belongs to the glycoside hydrolase family 43, GH43
evolution
the enzyme belongs to the glycoside hydrolase family 43, GH43, phylogenetic analysis and tree; the enzyme belongs to the glycoside hydrolase family 43, GH43, phylogenetic analysis and tree
evolution
the enzyme belongs to the glycoside hydrolase family 43, GH43, phylogenetic relationships of BLLJ_1840
evolution
the enzyme belongs to the glycosyl hydrolase family 30, GH30, subfamily 22. GH43_24 exo-beta-1,3-galactanase (Bl1,3Gal, EC 3.2.1.145) forms a gene cluster with GH30_5 and GH43_22 enzyme candidates, which are conserved in all Bifidobacterium longum strains; the enzyme belongs to the glycosyl hydrolase family 43, GH43, subfamily 24. GH43_24 exo-beta-1,3-galactanase (Bl1,3Gal) forms a gene cluster with GH30_5 exo-beta-1,6-galactobiohydrolase (Bl1,6Gal) and GH43_22 alpha-L-arabinofuranosidase (BlArafA) enzyme candidates, which are conserved in all Bifidobacterium longum strains
evolution
the enzyme belongs to the glycosyl hydrolase family 43, GH43. Structure comparisons reveal that structural and sequence homology between BbGal43A, Clostridium thermocellum Ct1,3Gal43A (PDB ID 3vsf), and Bacteroides thetaiotaomicron BT2959 (PDB ID 3nqh) indicate that all three enzymes might be different types of exo-beta-1,3-galactanase
metabolism
GH30_5 exo-beta-1,6-galactobiohydrolase (Bl1,6Gal, EC 3.2.1.145) and GH43_22 alpha-L-arabinofuranosidase (BlArafA, EC 3.2.1.55) are degradative enzymes for type II arabinogalactan (AG) side chains in cooperation with GH43_24 exo-beta-1,3-galactanase (Bl1,3Gal, EC 3.2.1.145); GH30_5 exo-beta-1,6-galactobiohydrolase (Bl1,6Gal, EC 3.2.1.145) and GH43_22 alpha-L-arabinofuranosidase (BlArafA, EC 3.2.1.55), which are degradative enzymes for type II arabinogalactan (AG) side chains in cooperation with GH43_24 exo-beta-1,3-galactanase (Bl1,3Gal, EC 3.2.1.145)
metabolism
the enzyme shows a synergistic effect with related enzymes on degradation of type II arabinogalactan

two modes of substrate binding are observed at the beta site of the CtCBM13 domain, and one galactobiose molecule is found in an L shaped pocket of the CtGH43 domain, which appears large enough to accommodate two more galactose units. Glu112 serves as the general base for substrate hydrolysis. Putative mechanism of substrate delivery via the CBM13 domain, overview
physiological function
type II arabinogalactan (AG) degradative enzymes, including Bl1,3Gal, Bl1,6Gal, and BlArafA. GH30_5 exo-beta-1,6-galactobiohydrolase (Bl1,6Gal, EC 3.2.1.145) and GH43_22 alpha-L-arabinofuranosidase (BlArafA, EC 3.2.1.55) are important for the acquisition of type II AG in Bifidobacterium longum
