1do8 Summary



The structure was published by Yang, Z., Floyd, D.L., Loeber, G., and Tong, L., in 2000 in a paper entitled "Structure of a closed form of human malic enzyme and implications for catalytic mechanism." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.2 Å and deposited in 1999.

The experimental data on which the structure is based was not deposited.
