Abstract |
---|
The structure of N-terminal domain was determined by NMR. It consists mainly of three alpha-helixes and one short beta-sheet, yet the N-terminal part remains unstructured. The cause of this flexibility is probably the His6-Tag attached at the N-terminus.The N-terminal domain of delta subunit was conquested to high-throughput screening (sitting drop), where several crystallization conditions were found.Higher quality crystals were obtained after 7-9 days with an average size 150 x 100 micrometers.Diffraction data were collected at ESRF Grenoble, ID-23. The resolution of the structure was 3.5 Angstrom. The data were processed by MOSFLM and the determination of the structure was done by molecular replacement with NMR structure used as a model. |

Struktura N-terminální domény byla určená NMR. Její struktura je tvořena 3 alfa-helixy a jedním krátkym beta-listem. Část domény zůstáva neuspořádaná, pravděpodobně díky flexibilnímu konci His6-Tag. Přistoupilo se ke krystalizaci N-terminální domény, kde byli najdeny krystalizační podmínky pro získání krystalu. Krystaly byli získany po 7-9 dnech s průměrnou velikostí 150 x 100 mikrometru. Difrakční data byli naměřeny na ESRF v Grenobli na ID-23. Rozlišení dat bylo 3.5 Angstrom. Data byli spracovány programem MOSFLM a struktura delta podjednotky byla určená molekulárním nahrazením za použití NMR struktury jako modelu. |
