ATP + L-tyrosine + tRNATyr = AMP + diphosphate + L-tyrosyl-tRNATyr
molecular dynamics simulations of TyrRS in its free form and complexed with Tyr, ATP, tyrosyl adenylate and inhibitor respectively are carried out to investigate the ligand-linked conformational stability changes associated with its catalytic cycle. Unliganded TyrRS samples a more relaxed conformational space than substrate-bound TyrRS. There are three high flexibility regions encompassing residues 114-118, 128-133, and 226-238 respectively. The region which includes the KFGKS motif shows the highest difference in fluctuations
