1qrk Summary


PDB entry 1qrk (supersedes 1bl2)


The structure was published by Fox, B.A., Yee, V.C., Pedersen, L.C., et al., Bishop, P.D., Stenkamp, R.E., and Teller, D.C., in 1999 in a paper entitled "Identification of the calcium binding site and a novel ytterbium site in blood coagulation factor XIII by x-ray crystallography." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.5 Å and deposited in 1999.

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