Descriptions
- Description Encodes a cytosolic protein with transglucosidase and amylomaltase activity. It is an essential component of the pathway from starch to sucrose and cellular metabolism in leaves at night. The protein binds to heteroglycans and utilizes glucose, mannose and xylose as acceptors. Fucose and galactose can also act as acceptors but less efficiently than the previous three. It was also was also recently reported to act on maltodextrins. On the other hand, arabinose and fructose were not efficiently used. Its role probably includes metabolizing maltose exported from the chloroplast. Studies using maltose extracted from the double mutant be2-1 be3-2 showed that this enzyme is preferentially active of, #946, -maltose. | disproportionating enzyme 2 (DPE2) | FUNCTIONS IN: 4-alpha-glucanotransferase activity, heteroglycan binding | INVOLVED IN: polysaccharide metabolic process, circadian rhythm, maltose catabolic process, maltose metabolic process, starch catabolic process | LOCATED IN: cytosol | EXPRESSED IN: 23 plant structures | EXPRESSED DURING: 13 growth stages | CONTAINS InterPro DOMAIN/s: Immunoglobulin-like fold , Carbohydrate-binding-like fold , Glycoside hydrolase, family 77 , Glycoside hydrolase, catalytic core , Glycoside hydrolase, carbohydrate-binding , Glycoside hydrolase, subgroup, catalytic core | BEST Arabidopsis thaliana protein match is: disproportionating enzyme
