Refinement of placental alkaline phosphatase complexed with nitrophenyl

The structure was published by Stec, B., Cheltsov, A., and Millan, J.L., in 2010 in a paper entitled "Refined structures of placental alkaline phosphatase show a consistent pattern of interactions at the peripheral site." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 2010.

This entry is a re-refinement of an older structure (1zeb) using the same experimental data but not carried out by the same authors.

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

The PDB entry contains the structure of Alkaline phosphatase, placental type. This molecule has the UniProt identifier P05187 (PPB1_HUMAN)search. The sample contained 484 residues which is 94% of the natural sequence. Out of 484 residues 481 were observed and are deposited in the PDB.

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.
