Crystal structure of E230Q mutant of cAMP-dependent protein kinase reveals unexpected apoenzyme conformation

The structure was published by Wu, J., Yang, J., Kannan, N., et al., Xuong, N.H., Ten Eyck, L.F., and Taylor, S.S., in 2005 in a paper entitled "Crystal structure of the E230Q mutant of cAMP-dependent protein kinase reveals an unexpected apoenzyme conformation and an extended N-terminal A helix." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.8 Å and deposited in 2004.

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

This PDB entry contains multiple copies of the structure of cAMP-dependent protein kinase, alpha-catalytic subunit.
