2.4.1.362 | synthesis |
alpha(1->2) or alpha(1->3) branched dextrans with high molar masses and controlled architecture are synthesized using dextransucrase from Oenococcous kitahare DSM 17330 (DSR-OK), the branching sucrase from Leuconostoc citreum NRRL B-1299 (BRS-A) and the branching sucrase from Leuconostoc citreum NRRL B-742 (BRS-BDELTA1), all in cell-free extract from recombinant Escherichia coli strain BL21. Their molecular structure, solubility, conformation, film-forming ability, as well as their thermal and mechanical properties are determined, detailed overview |
