ABSTRACT
|
|
|
|
| |
|
|
Rattlesnake venom lectin (RSL) from the western diamondback rattlesnake
(Crotalus atrox) is an oligomeric galactose-specific C-type lectin. The X-ray
crystal structure of RSL, in complex with lactose and thiodigalactoside, at 2.2
and 2.3 A resolution, respectively, reveals a decameric protein composed of two
5-fold symmetric pentamers arranged in a staggered, back-to-back orientation.
Each monomer corresponds to a single canonical C-type lectin carbohydrate
recognition domain devoid of accessory domains and is disulfide-bonded to a
monomer in the other pentamer. The structure is the first example of that of a
carbohydrate complex of a vertebrate galactose-specific C-type lectin. The 10
carbohydrate-binding sites, located on the rim of the decamer, suggest a role
for multivalent interactions and a mechanism for RSL's ability to promote
receptor cross-linking and cell aggregation.

The most recent references are shown first.
Citation data come partly from CiteXplore and partly
from an automated harvesting procedure. Note that this is likely to be
only a partial list as not all journals are covered by
either method. However, we are continually building up the citation data
so more and more references will be included with time.
Where a reference describes a PDB structure, the PDB
codes are
shown on the right.
