The structure of copper amine oxidase 1 from H. polymorpha in its metal-free precursor (apo) form is reported along with structures of the apo protein in complex with Cu^I and Co^II.

Hexameric rings of RadA recombinase from M. voltae have been crystallized. Structural comparisons suggest that homologues of RadA tend to form double-ringed assemblies.

The structure of the catalytic chain of Methanococcus jannaschii aspartate transcarbamoylase has been determined in a hexagonal crystal form and gives insight into the possible paths that the substrate carbamoyl phosphate may follow to reach the active site during catalysis.

A novel hyperactive antifreeze protein from R. inquisitor (RiAFP) has been overexpressed, purified and crystallized. A complete native X-ray diffraction data set was recorded to 1.3 Å resolution.

The major capsid proteins VP16 and VP17 of bacteriophage P23-77 have been crystallized using both recombinant and purified virus and preliminary diffraction analyses have been performed.

The expression, purification and crystallization of the alginate lyase AlgL from P. aeruginosa is described. The crystals diffracted to a resolution of 1.64 Å.

The utility of differential scanning fluorimetry for homogeneity assessment and crystallization improvement of PLP-dependent enzymes is demonstrated using the potential drug target BioA from M. tuberculosis.
