1rk2 Summary



The structure was published by Sigrell, J.A., Cameron, A.D., and Mowbray, S.L., in 1999 in a paper entitled "Induced fit on sugar binding activates ribokinase." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.25 Å and deposited in 1999.

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