2oat Summary



The structure was published by Storici, P., Capitani, G., Muller, R., Schirmer, T., and Jansonius, J.N., in 1999 in a paper entitled "Crystal structure of human ornithine aminotransferase complexed with the highly specific and potent inhibitor 5-fluoromethylornithine." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.95 Å and deposited in 1998.

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