The NMR and ITC analyses provided evidence for complexation of ASTX with Ca2+ in 1:2 stoichiometry via chelation at both carbonyl and hydroxyl groups. The rotation across torsion omega6 (C5-C6-C7-C8) upon complexation is consistent with the NOE between 7-H and 5-CH3. This study supports the inhibitory effect of ASTX on calcium-induced turbidity of lens crystallins. ------>tmu_sno=None ------>sno=16285 ------>authors2=Wu SH ------>authors3=Wu YY ------>authors4=Fang JM ------>authors5=Wu TH* ------>authors6= ------>authors6_c= ------>authors=Chen CS ------>delete_flag=0 ------>SCI_JNo=None ------>authors2_c= ------>publish_area=0 ------>updateTitle=Properties of astaxanthin/Ca2+ complex formation in the deceleration of cis/trans isomerization. ------>language=2 ------>check_flag=None ------>submit_date=None ------>country=None ------>no=16 ------>patent_SDate=None ------>update_bywho=None ------>publish_year=2007 ------>submit_flag=None ------>publish_month=7 |
