Preparation, purification, crystallization and X-ray diffraction analysis of PicW2 from Picea wilsonii

Dehydrin proteins are generally induced in response to low temperature stress. PicW2 is a dehydrin protein and its expression is associated with cold hardiness. To understand the low temperature tolerance mechanism, prokaryotically expressed PicW2 protein was purified using chitosan affinity chromatography and gel filtration, crystallized using the vapour-diffusion method. Finally, we got the crystallographic information and analysed the result of X-ray diffraction.

Crystallographic analysis of the Staphylococcus epidermidis lipase involved in esterification in aqueous solution

The Staphylococcus epidermidis lipase (SeLip, GehC) can be used in flavour-compound production via esterification in aqueous solution. This study reports the crystallization and crystallographic analysis of recombinant GehC (rGehC; Lys303–Lys688) with a molecular weight of 43 kDa. rGehC was crystallized at 293 K using PEG 10 000 as a precipitant, and a 99.9% complete native data set was collected from a cooled crystal at 77 K to a resolution of 1.9 Å with an overall Rmerge value of 7.3%. The crystals were orthorhombic and belonged to space group P212121, with unit-cell parameters a = 42.07, b = 59.31, c = 171.30 Å, α = β = γ = 90°. Solvent-content calculations suggest that there is likely to be one lipase subunit in the asymmetric unit.
