Crystal structure of GAD1 from Arabidopsis thaliana

The structure was published by Gut, H., Dominici, P., Pilati, S., et al., Svergun, D.I., Grutter, M.G., and Capitani, G., in 2009 in a paper entitled "A common structural basis for pH- and calmodulin-mediated regulation in plant glutamate decarboxylase." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.672 Å and deposited in 2009.

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

This PDB entry contains multiple copies of the structure of Glutamate decarboxylase 1.

The molecule most likely forms homohexamers.
