Tyrosyl-tRNA synthetase from Thermus thermophilus complexed with wild-type tRNAtyr(GUA) and with ATP and tyrosinol

The structure was published by Yaremchuk, A., Kriklivyi, I., Tukalo, M., and Cusack, S., in 2002 in a paper entitled "Class I Tyrosyl-tRNA Synthetase Has a Class II Mode or tRNA Recognition" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.9 Å and deposited in 2002.

The experimental data on which the structure is based was also deposited.

This PDB entry contains a complex of 2 biomacromolecules, namely TYROSYL-TRNA SYNTHETASE and WILD-TYPE TRNATYR(GUA).

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule most likely forms heterotetramers.
