SIALIDASE L FROM LEECH MACROBDELLA DECORA

The structure was published by Luo, Y., Li, S.C., Chou, M.Y., Li, Y.T., and Luo, M., in 1998 in a paper entitled "The crystal structure of an intramolecular trans-sialidase with a NeuAc alpha2-->3Gal specificity." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 1997.

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

The PDB entry contains the structure of SIALIDASE L. This molecule has the UniProt identifier Q27701 (NANL_MACDE)search. The sample contained 679 residues which is 92% of the natural sequence. Out of 679 residues 679 were observed and are deposited in the PDB.

The molecule is most likely monomeric.
