酵母中的起源识别复合体(ORQ)由6个 亚单位。他们正试图将其晶化以确定其 用X-射线结晶学分析了其结构。与此同时,他们想要 用-STEM测定络合物的化学计量比。 初步结果在一定程度上令人鼓舞,尽管 复杂的似乎:要在碳支撑膜上分崩离析,似乎是 通过短暂的戊二醛固定保存得相当好。这两个 ORC单独和ORC+DNA将被研究
英文摘要
The origin recognition complex (ORQ in yeast is composed of six subunits. They are attemptmg to crystallize it to determme its structure by x-ray crystallography. Meanwhile, they would like to determine the stoichiometry of the complex using-the STEM. Preliminary results have been somewhat encouragmg, in that while the complex seems:to fall apart on the carbon support film, it seems to be fairly well-preserved by a brief glutaraldehyde fixation. Both the ORC alone and the ORC plus DNA will be looked at
