oligosaccharide 4-alpha-D-glucosyltransferase EC#: 2.4.1.161; 凯望编码 (ChemWhat Code): 1377453
| 英文名 | oligosaccharide 4-alpha-D-glucosyltransferase |
| Example Structure |  |
| 别名 | 1,4-alpha-glucan:1,4-alpha-glucan 4-alpha-glucosyltransferase, amylase III |
| EC Number | 2.4.1.161 |
| CAS编号 | 9000-92-4 |
| Comments | The enzyme acts on amylose, amylopectin, glycogen and maltooligosaccharides. No detectable free glucose is formed, indicating the enzyme does not act as a hydrolase. The enzyme from the bacterium Cellvibrio japonicus has the highest activity with maltotriose as a donor, and also accepts maltose [3], while the enzyme from amoeba does not accept maltose [1,2]. Oligosaccharides with 1¡ú6 linkages cannot function as donors, but can act as acceptors [3]. Unlike EC 2.4.1.25, 4-¦Á-glucanotransferase, this enzyme can transfer only a single glucosyl residue. |

| History | |
| Reactions | Transfers the non-reducing terminal alpha-D-glucose residue from a (1->4)-alpha-D-glucan to the 4-position of a free glucose or of a glucosyl residue at the non-reducing terminus of a (1->4)-alpha-D-glucan, thus bringing about the rearrangement of oligosaccharides. |
