The relationship of macro biomolecular structure and
function is veryimportant in the biological and
biochemical system. Because of macrobiomolecular
complexity, it is difficult to observe and analyze their
threedimension conformations and quaternary structures. In
order to solve theseproblems, we can use picture presentation
to study and compare the structuresof macro biomolecules such
as proteins and nucleic acids. The Protein
Data Bank (PDB) archive of the Brookhaven National Laboratory(
BNL) is a computer-based archival file for macromolecular
structures. The Bankstores in a uniform format atomic
coordinates and partial bond connectivities,as derived from
crystallographic and NMR studies. For a number of years,
thePDB has been available on the internet for access via
FTP, more recentlythrough Gopher, and now via WWW. These tools
provided access to the individualentries of PDB and allowed
limited searches of the data bank. We develop a
personal computer based program which can read in
molecularcoordinate files in PDB formats and interactively
displays the molecule on themonitor screen. This program is
written in the Visual Basic language and usesthe Windows
graphics user interface. The Program can run on IBM PC
compatiblepersonal computers under Microsoft Windows 3.X,
Windows 95 and Windows NTsystems.
This program uses chromatic anaglyph method to display
stereo macrobiomolecular structures. Using this program,
each macro biomolecule can beviewed in three dimensional
model and can be moved, scaled and rotated aboutthree
orthogonal axes.
