HUMAN GROWTH HORMONE BOUND TO SINGLE RECEPTOR

The structure was published by Clackson, T., Ultsch, M.H., Wells, J.A., and de Vos, A.M., in 1998 in a paper entitled "Structural and functional analysis of the 1:1 growth hormone:receptor complex reveals the molecular basis for receptor affinity." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.6 Å and deposited in 1998.

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

This PDB entry contains a complex of 2 biomacromolecules, namely GROWTH HORMONE and GROWTH HORMONE RECEPTOR.
