CRYSTAL STRUCTURE OF GLUTAMATE-1-SEMIALDEHYDE AMINOMUTASE (AMINOTRANSFERASE, WILD-TYPE FORM)

The structure was published by Hennig, M., Grimm, B., Contestabile, R., John, R.A., and Jansonius, J.N., in 1997 in a paper entitled "Crystal structure of glutamate-1-semialdehyde aminomutase: an alpha2-dimeric vitamin B6-dependent enzyme with asymmetry in structure and active site reactivity." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.4 Å and deposited in 1997.

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