Crystal Structure of Phosponoacetaldehyde Hydrolase Complexed with Magnesium and the Inhibitor Vinyl Sulfonate

The structure was published by Morais, M.C., Zhang, G., Zhang, W., Olsen, D.B., Dunaway-Mariano, D., and Allen, K.N., in 2004 in a paper entitled "X-ray crystallographic and site-directed mutagenesis analysis of the mechanism of Schiff-base formation in phosphonoacetaldehyde hydrolase catalysis" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.4 Å and deposited in 2003.

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

This PDB entry contains multiple copies of the structure of Phosphonoacetaldehyde Hydrolase.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.
