PURIFICATION (Commentary)
ORGANISM
UNIPROT
LITERATURE
ADP-glucose utilizing activity partially, UDP-glucose utilizing activity 368.7fold to homogeneity
-
partially from dried starch granules isolated from developing embryos, solubilization with alpha-amylase, and anion chromatography
-
partially from lyophilized starch extracted from developing embryos, by anion exchange chromatography
-
partially from starch granules of mature seeds, solubilization and SDS-PAGE
recombinant His-tagged GBSSI catalytic domain, residues Met83-Pro609, from Escherichia coli strain BL21 by nickel affinity chromatography and gel filtration
soluble and starch granule-bound proteins are extracted from developing endosperms
