The structure was published by Rupp, B., Marshak, D., and Parkin, S., in 1996 in a paper entitled "Crystallization and Preliminary X-Ray Analysis of Two New Crystal Forms of Calmodulin" (abstract).
This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 2003.
The experimental data on which the structure is based was also deposited.
