Asymmetry of tyrosyl-tRNA synthetase in solution

The tyrosyl-tRNA synthetase from Bacillus stearothermophilus crystallizes as a symmetrical dimer with each subunit having a complete active site. The enzyme-substrate complexes, however, are known to be asymmetrical in solution because the enzyme exhibits half-of-the-sites activity by binding tightl...
