1b0k Summary


PDB entry 1b0k (supersedes 1as9)


The structure was published by Lloyd, S.J., Lauble, H., Prasad, G.S., and Stout, C.D., in 1999 in a paper entitled "The mechanism of aconitase: 1.8 A resolution crystal structure of the S642a:citrate complex." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.5 Å and deposited in 1998.

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

The PDB entry contains the structure of PROTEIN (ACONITASE). This molecule has the UniProt identifier P16276 (ACON_PIG)search. The sample contained 753 residues which is 96% of the natural sequence. Out of 753 residues 753 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 is most likely monomeric.
