  • RIKEN Structural Genomics Beamlines have been constructed for the crystallographic analysis in the structural genomics research at synchrotron radiation facility SPring-8. Synchrotron radiation accelerates the crystallographic analysis of protein structure. The target of the research and development is focused on the automatic beamline operation to maximize beamline efficiency. We are developing the sample management system, which is composed of the sample auto-changer and the database system, for high-throughput data collection. The sample management system and the beamline operating system make it possible to execute automatic data collection without any operators. The beamlines will be ready for user operation in autumn 2002. The concept of automatic beamline operation and the present status of RIKEN Structural Genomics Beamlines will be presented.

  • 액상 x-선 소각산란법을 이용하여 단백질의 구조를 분석하였다. 사용한 단백질은 구조가 이미 알려진 Lysozyme과 $Bcl-XL(\vartriangle TM/\vartriangle loop)$ 그리고 $Bcl-XL(\vartriangle TM/\vartriangle loop))$에 자유롭게 움직이는 고리를 가진 $Bcl-XL(\vartriangleTM))$이다. Lysozyme와 $Bcl-XL(\vartriangle TM/\vartriangle loop)$에 대한 소각산란결과는 단백질 결정학으로부터 알려진 분자구조에서 얻은 이론적인 결과와 농도에 의한 차이정도를 제외하고는 잘 일치하였다. $Bcl-XL(\vartriangleTM))$의 경우는 단백질 결정산란 신호에서 볼 때 $Bcl-XL(\vartriangle TM/\vartriangle loop)$와 차이가 없는 것으로 알려져 있으나, 소각산란에서는 뚜렷한 차이를 나타내는 결과를 얻어 loop와 같이 쉽게 움직이는 부분을 가진 단백질을 연구하는 경우 소각산란의 장점을 확인할 수 있었다. 위 실험을 통하여 포항 가속기 연구소 4C1 빔라인의 성능은 적어도 해상도 $\sim2.2\;nm$까지 용액상의 단백질 구조를 분석할 수 있다는 것을 확인하였다.

  • The White Beamline of the Pohang Accelerator Laboratory(PAL) consists of main and second slits, a microprobe system, two ion chambers, a video-microscope, and a Si(Li) detector. These machine components must be controlled remotely through computer system to make user experiments precise and speedy. A real-time computer control system was developed to control and monitor these machine components. A VNIEbus computer with OS-9 real-time operating system was used for low-level data acquisition and control. VME I/O modules were used for step motor control and scaler control. The software has modular structure for maximum performance and easy maintenance. We developed database, I/O driver, and control software. We used PC/Window95 for data logging and operator interface. Visual C++ was used graphical user interface programming. RS232C was used for communication between VME and PC.
