Crystal Structure Analysis of SERA5E from plasmodium falciparum

The structure was published by Hodder, A.N., Malby, R.L., Clarke, O.B., et al., Colman, P.M., Crabb, B.S., and Smith, B.J., in 2009 in a paper entitled "Structural Insights into the Protease-like Antigen Plasmodium falciparum SERA5 and Its Noncanonical Active-Site Serine" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.8 Å and deposited in 2008.

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

The PDB entry contains the structure of Serine-repeat antigen protein. This molecule has the UniProt identifier Q9TY95 (SERA_PLAF7)search. The sample contained 265 residues which is < 90% of the natural sequence. Out of 265 residues 249 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.
