The solution structure of A. thaliana protein At5g39720.1 reported here is the first for a member of the AIG2-like family (PF06094). The three-dimensional structure shows similarity to those determined for members of the uncharacterized Pfam family UPF0131.
The structure of the PII signal transduction protein of N. meningitidis at 1.85 Å resolution is described.
The crystal structure of a conserved hypothetical protein from X. campestris has been determined to a resolution of 1.6 Å. The determined X. campestris structure shows that it belongs to the superfamily of serine α/β hydrolase, with an extra strand preceding the first β-strand to lead to extensive subunit interactions in the crystal.
Attempts to crystallize a complex of papain (C. papaya) with a cysteine protease inhibitor from the parasitic pathogen T. brucei failed. However, over an extended period the mixture produced an ordered crystal of the protease carrying two peptide fragments in the active site. These correspond to dipeptides and tripeptides that are assigned as fragments of the inhibitor, which has presumably suffered...
Data to a maximum of 2.7 Å resolution have allowed a more accurate model of the extracellular domains of the β common cytokine receptor to be determined. Structural details of the membrane-distal BC and FG loops of domain 4 and loops AB and EF of domain 1, which have been implicated in high-affinity binding, are much better defined, revealing a more compact functional epitope....

The N-terminal, cytoplasmic domain of the Na+-coupled HCO3 cotransporter NBCe1-A crystallizes in the trigonal space group P3121 or P31 with pseudo P3121 symmetry and diffracts X-rays to 3.0 Å resolution. The crystal packing demonstrates a domain-swap mechanism for dimerization.
Crystallization and X-ray data analyses were successful for both Ca2+-independent and Ca2+-dependent species of the type II antifreeze protein. The resolution of the crystal was 1.35 Å for the Ca2+-independent species, and was 1.25 and 1.06 Å for the Ca2+-dependent species in the Ca2+-free and -bound states, respectively.
