==PHYTOHEMAGGLUTININ-L==
-
The structure of phytohemagglutinin-L (PHA-L), a leucoagglutinating seed, lectin from Phaseolus vulgaris, has been solved with molecular replacement, using the coordinates of lentil lectin as model, and refined at a, resolution of 2.8 A. The final R-factor of the structure is 20.0%. The, quaternary structure of the PHA-L tetramer differs from the structures of, the concanavalin A and peanut lectin tetramers, but resembles the, structure of the soybean agglutinin tetramer. PHA-L consists of two, canonical legume lectin dimers that pack together through the formation of, a close contact between two beta-strands. Of the two covalently bound, oligosaccharides per monomer, only one GlcNAc residue per monomer is, visible in the electron density. In this article we describe the structure, of ...
