A three-dimensional protein graphic program

Abstract A FORTRAN program was developed to generate the three-dimensional vector graphics of protein molecules. The program used DISSPLA subroutines (Computer Associates International Inc.) to interface the computer system for graphic display. Two data formats supported by the program were the X-ray crystallographic protein data and the structure data from the program PROADS. A protein molecule was interactively rotated or enlarged for display. The program provides a simple solution to the need of pr... Title of program: PROPLT Catalogue Id: ABTB_v1_0 Nature of problem Three-dimensional structure of a protein is displayed by a vector graphic algorithm. A protein molecule can be interactively rotated to show a three-dimensional image in any orientation. The protein molecule can also be enlarged allowing user to focus on a specific part of the molecule. Two data formats are supported by the program. They are the X-ray crystallographic protein structure coordinates from Brookhaven Protein Data Bank in New York, U.S.A., and the protein structure data format of the ...

**摘要** 本研究开发了一款FORTRAN程序，用于生成蛋白质分子的三维矢量图形。该程序借助DISSPLA子程序（计算机联合国际公司，Computer Associates International Inc.）实现与计算机图形显示系统的接口适配。程序支持两种数据格式：X射线晶体学蛋白质数据，以及来自PROADS程序的结构数据。用户可通过交互操作对蛋白质分子进行旋转或放大以实现可视化展示，本程序为相关需求提供了简洁的解决方案（原文末尾存在截断）。

**程序名称**：PROPLT
**目录编号**：ABTB_v1_0
**问题本质**：本程序采用矢量图形算法实现蛋白质三维结构的可视化展示。用户可交互式旋转蛋白质分子，以任意视角呈现其三维图像；亦可对分子进行放大操作，以便聚焦观察分子的特定区域。程序支持两种数据格式：来自美国纽约布鲁克黑文蛋白质数据库（Brookhaven Protein Data Bank）的X射线晶体学蛋白质结构坐标数据，以及PROADS程序的蛋白质结构数据格式（原文末尾存在截断）。
