Some applications of computer model-building in polysaccharide biochemistry

Molecular model-building by computer.

Many problems of modern biology are concerned with the detailed relation between biological function and molecular structure. Some of the questions currently being asked will be completely answered only when one has an understanding of the structure of all the molecular components of a biological system and a knowledge of how they interact. There are, of course, a large number of problems in bi...

The biochemistry and genetics of capsular polysaccharide production in bacteria.

Bacterial polysaccharides are usually associated with the outer surface of the bacterium. They can form an amorphous layer of extracellular polysaccharide (EPS) surrounding the cell that may be further organized into a distinct structure termed a capsule. Additional polysaccharide molecules such as lipopolysaccharide (LPS) or lipooligosaccharide (LOS) may also decorate the cell surface. Polysac...

Computer-aided cryptography: some tools and applications

3-D model building for computer vision

This paper presents a Computer-Aided Geometric Design (CAGD) based approach for building 3-D models which can be used for the recognition of 3-D objects for industrial machine vision applications. The objects are designed using the Alpha_1 CAGD system developed at the University of Utah. A new method is given which uses the CAGD design and allows the points on the surface of the object to be sa...

Solution of some equations in Biochemistry

It is possible to write down the equations governing a one-stage enzyme-catalysed reaction (according to Michaelis-Menton kinetics) quite easily, and deduce information about the steady-state flow in such a system. The situation is somewhat more complicated if several such reactions form a linear chain. We have applied Gröber-basis techniques to solve such systems. Introduction. If we consider ...
