Class
Transferases;
Glycosyltransferases;
Hexosyltransferases
BRITE hierarchy
Sysname
2-alpha-D-glucosyl-D-glucose:phosphate beta-D-glucosyltransferase
Reaction(IUBMB)
2-alpha-D-glucosyl-D-glucose + phosphate = D-glucose + beta-D-glucose 1-phosphate [RN:R07264]
Reaction(KEGG)
Substrate
2-alpha-D-glucosyl-D-glucose [CPD:C15548];
phosphate [CPD:C00009]
Product
D-glucose [CPD:C00031];
beta-D-glucose 1-phosphate [CPD:C00663]
Comment
The enzyme from Thermoanaerobacter brockii can act with alpha-1,2-oligoglucans, such as selaginose, as substrate, but more slowly. The enzyme is inactive when dissaccharides with linkages other than alpha-1,2 linkages, such as sophorose, trehalose, neotrehalose, nigerose, laminaribiose, maltose, cellobiose, isomaltose, gentiobiose, sucrose and lactose, are used as substrates.
