The first crystal structure of the kinase domain of tau tubulin kinase 2 in complex with a small-molecule inhibitor is described.
PDB reference: TTBK2 kinase domain, complex with WHI-P180, 6u0k
The crystal structure of mitochondrial citrate synthase 4 from Arabidopsis thaliana was determined at a resolution of 2.69 Å and is the first structure of a plant mitchondrial citrate synthase.
PDB reference: citrate synthase 4, 6k5v

The omalizumab Fab was engineered to disrupt recurring crystal packing interactions in Fab crystal structures; this led to the eventual structure determination of an omalizumab-derived Fab in complex with its target, IgE-Fc.
The structure of the human TRPV1 ankyrin-repeat domain was determined by X-ray crystallography. This structure showed a unique solvent-accessible pocket near Cys258 and a unique conformation of its finger loop 3, the conformation of which is significantly different from that in the rat homologue.
PDB reference: ligand-free human TRPV1 ankyrin-repeat domain, 6l93
The Legionella pneumophila phospholipase named PlaA is a secreted effector that plays an essential role in maintaining the integrity of Legionella-containing vacuoles in L. pneumophila pathogenesis. Crystals of PlaA and its selenomethionine-substituted form were used for X-ray analysis and diffracted to resolutions of 2.2 and 2.7 Å, respectively.
Crystal structures of Bacillus subtilis BacF provide an insight into stereospecific substrate recruitment in a fold type I transaminase enzyme.
The structure of neutral invertase 2 from Arabidopsis thaliana was solved at 3.4 Å resolution. This first structure of a GH100 family enzyme from a higher plant reveals a remarkable similarity to that of the neutral invertase InvA from the cyanobacterium Anabaena, pointing to high evolutionary conservation.
