The molecular structure of a triclinic crystal form of concanavalin A has, been refined at 2.4 A resolution. The crystals have unit cell dimensions a, = 78.8 A, b = 79.3 A, c = 133.3 A, alpha = 97.1degrees, beta =, 90.2degrees, and gamma = 97.5degrees and contain two tetramers per, asymmetric unit each with approximate 222 symmetry. The final, crystallographic R-factor is 0.205 and the free-R-factor is 0.265 in the, resolution range 6.0 to 2.4 A. The conformation of the tetramer is more, similar to that found in concanavalin A saccharide complexes than in the, previously reported I222 crystal form of uncomplexed concanavalin A. A, comparison of the molecular packing between the two crystal forms shows a, more open arrangement with large solvent channels through the crystal.

A TRICLINIC CRYSTAL FORM OF THE LECTIN CONCANAVALIN A

Overview

The molecular structure of a triclinic crystal form of concanavalin A has been refined at 2.4 A resolution. The crystals have unit cell dimensions a = 78.8 A, b = 79.3 A, c = 133.3 A, alpha = 97.1degrees, beta = 90.2degrees, and gamma = 97.5degrees and contain two tetramers per asymmetric unit each with approximate 222 symmetry. The final crystallographic R-factor is 0.205 and the free-R-factor is 0.265 in the resolution range 6.0 to 2.4 A. The conformation of the tetramer is more similar to that found in concanavalin A saccharide complexes than in the previously reported I222 crystal form of uncomplexed concanavalin A. A comparison of the molecular packing between the two crystal forms shows a more open arrangement with large solvent channels through the crystal.
