spacer

chicken c-Src kinase domain in complex with ATPgS

The structure was published by Azam, M., Seeliger, M.A., Gray, N.S., Kuriyan, J., and Daley, G.Q., in 2008 in a paper entitled "Activation of tyrosine kinases by mutation of the gatekeeper threonine." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.3 Å and deposited in 2008.

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

This PDB entry contains multiple copies of the structure of Proto-oncogene tyrosine-protein kinase Src.

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