  ABSTRACT  
 
The K(bm1) and K(bm8) natural mutants of the murine MHC class I molecule H-2K(b) were originally identified by allograft rejection. They also bind viral peptides VSV8 and SEV9 with high affinity, but their peptide complexes have substantially decreased thermostability, and the K(bm1) complexes do not elicit alloreactive T cell responses. Crystal structures of the four mutant complexes at 1.7-1.9 A resolution are similar to the corresponding wild-type K(b) structures, except in the vicinity of the mutated residues, which alter the electrostatic potential, topology, hydrogen bonding, and local water structure of the peptide binding groove. Thus, these natural K(b) mutations define the minimal perturbations in the peptide environment that alter antigen presentation to T cells and abolish alloreactivity.

Figure 1. Molecular Structure of K^b and Location of the Mutations in K^bm1 and K^bm8(A) Ribbon diagram of wild-type K^b with peptide (magenta) bound in an extended conformation within the binding groove formed by the α helices and the β sheet floor.(B) Mutated side chains in K^bm1 and K^bm8 are shown in green and orange, respectively, while wild-type side chains are shown in (A).(C) Superimposed Cα tracings of the α[1]α[2] helices of K^b-VSV8 (yellow), K^b-SEV9 (blue), K^bm1-VSV8 (magenta), K^bm1-SEV9 (red), K^bm8-VSV8 (cyan), and K^bm8-SEV9 (green). Peptide-contacting side chains from the helices, some of which have different conformations in the six complexes, are shown
Figure 5.
Figure 5. Comparison of the Interactions at the K^bm8 Mutation Site with K^bThe coloring scheme is the same as in Figure 4 except that the MHC residues at the mutation site are colored orange. The two conformers of Ser-24 in K^bm8-VSV8 are shown in orange and blue. Note the intricate hydrogen bond networks mediated by water molecules at the K^bm8 mutation sites compared to the equivalent wild-type K^b complexes

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.
