galactan + H2O | initially, rather long oligosaccharides are detected as hydrolysis products of potato galactan. Then, as the reaction proceeds, mainly galactotetraose is produced. After 24 h reaction, D-galactose, beta-1,4-D-galactobiose, beta-1,4-D-galactotriose and beta-1,4-D-galactotetraose are detected as the major products from potato galactan. The enzyme hydrolyzes galactans more efficiently than pectic galactans | Thermotoga maritima | ? | - |
