| 3.2.1.145 | beta-(1-3)-D-galactotriose + H2O |
relative activity: 119%. Enzyme hydrolyzes beta-1,3-linked galacto-oligosaccharides but does not hydrolyze beta-1,4-linked and beta-1,6-linked galacto-oligosaccharide. Ct1,3Gal43A also can not hydrolyze the beta-1,3-galactosyl linkage of beta-1,3-galactosyl galactosaminide, beta-1,3-galactosyl glucosaminide, or beta-1,3-galactosyl L-arabinofuranoside |

| 3.2.1.145 | beta-1,3-galactan + H2O |
relative activity: 100%. Enzyme catalyzes hydrolysis only of beta-1,3-linked galactosyl oligosaccharides and polysaccharides. Enzyme does not hydrolyze beta-1,4-linked galactose-containing polysaccharides, such as pectic galactan and alpha-L-arabinofuranosidase-treated pectic galactan from lupine, and also does not hydrolyze laminarin, CM-curdlan, or beta-1,3-xylan, suggesting that the enzyme acts only on a beta-1,3-linked galactan chain |

| 3.2.1.145 | more |
the enzyme specifically hydrolyses beta-1,3 glycosidic bonds in galactose-based oligosaccharides or polysaccharides, and shows maximum activity towards beta-1,3-D-galactotetraose. The enzyme also can perform beta-1-3 linked main chain hydrolysis in the presence of a beta-1,6 linked branch |
