1ay4 Summary



The structure was published by Okamoto, A., Nakai, Y., Hayashi, H., Hirotsu, K., and Kagamiyama, H., in 1998 in a paper entitled "Crystal structures of Paracoccus denitrificans aromatic amino acid aminotransferase: a substrate recognition site constructed by rearrangement of hydrogen bond network." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.33 Å and deposited in 1997.

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