E. COLI ALKALINE PHOSPHATASE MUTANT (D153GD330N) COMPLEX WITH PHOSPHATE

The structure was published by Le Du, M.H., Lamoure, C., Muller, B.H., et al., Lajeunesse, E., Menez, A., and Boulain, J.C., in 2002 in a paper entitled "Artificial evolution of an enzyme active site: structural studies of three highly active mutants of Escherichia coli alkaline phosphatase." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.5 Å and deposited in 2001.

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

This PDB entry contains multiple copies of the structure of Alkaline phosphatase.

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

The molecule most likely forms homodimers.
