The product of the human leukocyte antigen (HLA) gene HLA-B*2703 differs from that of the prototypical subtype HLA-B*2705 by a single amino acid at heavy-chain residue 59 that is involved in anchoring the peptide N-terminus within the A pocket of the molecule. Two B*2703–peptide complexes were crystallized using the hanging-drop vapour-diffusion method using PEG 8000 as a precipitant. A pocket...

Thioredoxin reductase 1 (Trr1) from S. cerevisiae is a component of the thioredoxin system, which is involved in several biological processes, including the reduction of disulfide bonds and response to oxidative stress. The expression, purification, crystallization and preliminary X-ray crystallographic studies of yeast Trr1 are reported.
In order to clarify the structural basis of the pathogenesis-related-1 domain, Na-ASP-1, the first multi-domain ASP from the human hookworm parasite N. americanus, has been crystallized. 2.2 Å resolution data have been collected from a crystal belonging to the monoclinic space group P21.
