  1. BN, Borrelidin; ThrRS, threonyl-tRNA synthetase.
  2. *This crystal was co-crystallized with BN in the presence of threonine, AMPcPP and MgCl2. No electric density of these substrates was observed.
  3. The crystal was co-crystallized with BN without the presence of threonine, AMPcPP or MgCl2.
  4. Values in parentheses are for highest-resolution shell.
