1v74 Summary


ribonuclease-inhibitor complex

The structure was published by Graille, M., Mora, L., Buckingham, R.H., Van Tilbeurgh, H., and De Zamaroczy, M., in 2004 in a paper entitled "Structural inhibition of the colicin D tRNase by the tRNA-mimicking immunity protein" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 2003.

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

This PDB entry contains a complex of 2 biomacromolecules, namely Colicin D and Colicin D immunity protein.

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.
