Abstract

In view of the biological significance of understanding the ribosomal machinery of both prokaryotes and eukaryotes, the L30e ribosomal protein from Methanocaldococcus jannaschii was cloned, overexpressed, purified and crystallized using the microbatch-under-oil method with the crystallization conditions 40% PEG 400, 0.1 M MES pH 6.0 and 5% PEG 3000 at 291 K. A diffraction-quality crystal (0.20 × 0.20 × 0.35 mm) was obtained that belonged to the primitive tetragonal space group P43, with unit-cell parameters a = 46.1, b = 46.1, c = 98.5 \AA, and diffracted to a resolution of 1.9 \AA. Preliminary calculations reveal that the asymmetric unit contains two monomers with a Matthews coefficient $(V_M)$ of 2.16 $\AA^3 Da^{-1}$.
