| - | '''Beta-1,4-galactanase''' (BGAL) is a cell-wall-degrading enzyme. BGAL hydrolyses β-1,4-galactan in the hairy regions of pectin. Specific galactanases exist for hydrolysing β-1,3, β-1,4, β-1,5 and β-1,6 galacto-pyranosyl linkages. These enzymes degrade D-galactan to produce D-galactose and D-galacto-oligosaccharides.
