1euu Summary



The structure was published by Gaskell, A., Crennell, S., and Taylor, G., in 1995 in a paper entitled "The three domains of a bacterial sialidase: a beta-propeller, an immunoglobulin module and a galactose-binding jelly-roll." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.5 Å and deposited in 1996.

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 Q02834 (NANH_MICVI)search. The sample contained 605 residues which is 99% of the natural sequence. Out of 605 residues 601 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.
