... of the C-termi-nal domain in the T and TG structures suggests a revised F structure (PDB 3if5). There are disordered regions in the F (3 54- 403 and 44 9- 45 6 aa), N (3 54- 376, 395 -40 1 and 44 6 -45 6 ... (3 34, 336-338, 344 , 41 9, 42 0, 42 2 and 42 8 aa; nine aa in total) were locatednear the interface of the physiological dimer. The C-terminal domain may contain structural featuresinvolved in ... state(disordered in the ligand-free state in YbgJ). In the absence of the ligand, the lid part is separated from the active site, which leads to a more open active site.Upon the binding of ligand in the...
