== Publication Abstract from PubMed == | |||
Two new crystal structures of Bacillus stearothermophilus tryptophanyl-tRNA synthetase (TrpRS) afford evidence that a closed interdomain hinge angle requires a covalent bond between AMP and an occupant of either pyrophosphate or tryptophan subsite. They also are within experimental error of a cluster of structures observed in a nonequilibrium molecular dynamics simulation showing partial active-site assembly. Further, the highest energy structure in a minimum action pathway computed by using elastic network models for Open and Pretransition state (PreTS) conformations for the fully liganded TrpRS monomer is intermediate between that simulated structure and a partially disassembled structure from a nonequilibrium molecular dynamics trajectory for the unliganded PreTS. These mutual consistencies provide unexpected validation of inferences drawn from molecular simulations. | |||
Independent saturation of three TrpRS subsites generates a partially assembled state similar to those observed in molecular simulations.,Laowanapiban P, Kapustina M, Vonrhein C, Delarue M, Koehl P, Carter CW Jr Proc Natl Acad Sci U S A. 2009 Feb 10;106(6):1790-5.
