Abstract
Deoxyuridine triphosphate nucleotidohydrolase (dUTPase), an enzyme in the nucleotide metabolism that is a pyrophosphatase hydrolyzing dUTP, has been crystallized. The crystals belong to the trigonal space group R3 and diffract beyond 2 A. The native dUTPase crystals and a mercury derivative are stable in the X-ray beam and are suitable for a high resolution X-ray structure analysis.
摘要
脱氧尿苷三磷酸核苷酸水解酶（dUTPase），一种核苷酸代谢中的酶，是一种水解dUTP的焦磷酸酶，已被结晶。这些晶体属于三方晶系空间群R3，衍射极限超过2埃。天然dUTPase晶体和汞衍生物在X射线束中稳定，适用于高分辨率X射线结构分析。
