Trypanosoma rangeli sialidase in complex with DANA

The structure was published by Amaya, M.F., Buschiazzo, A., Nguyen, T., and Alzari, P.M., in 2003 in a paper entitled "The high resolution structures of free and inhibitor-bound Trypanosoma rangeli sialidase and its comparison with T. cruzi trans-sialidase" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.1 Å and deposited in 2002.

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

The PDB entry contains the structure of Sialidase. This molecule has the UniProt identifier O44049 (O44049_TRYRA)search. The sample contained 641 residues which is 100% of the natural sequence. Out of 641 residues 625 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.
