Motion in Trp RNA-binding attenuation protein [trprbatten]

[ jump to morphs ]

Classification Suspected Domain Motion, Hinge Mechanism [D-h-1]

1WAP With tryptophan [ PartsList ]

Trp RNA-binding attenuation protein's eleven subunits are stabilized through eleven intersubunit beta-sheets to form a beta-wheel structure with a large central hole. The nature of binding of L-tryptophan in the clefts between adjacent beta-sheets in the beta-wheel suggested to Antson et al. (1995) that this binding induces conformation changes in the flexible residues 25-33 and 49-52 (presumably hinges). To date (Sept 1997) only one crystal structure has been solved.
