1euy Summary



The structure was published by Sherlin, L.D., Bullock, T.L., Newberry, K.J., et al., Beijer, B., Sproat, B.S., and Perona, J.J., in 2000 in a paper entitled "Influence of transfer RNA tertiary structure on aminoacylation efficiency by glutaminyl and cysteinyl-tRNA synthetases." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.6 Å and deposited in 2000.

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

This PDB entry contains a complex of 2 biomacromolecules, namely GLUTAMINYL TRNA and GLUTAMINYL-TRNA SYNTHETASE.

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 heterodimers.
