Abstract
An optimized self-organizing map algorithm has been used to obtain
protein topological (proteinotopic) maps. A neural network is able to
arrange a set of proteins depending on their ultraviolet circular
dichroism spectra in a completely unsupervised learning process.
Analysis of the proteinotopic map reveals that the network extracts the
main secondary structure features even with the small number of examples
used. Some methods to use the proteinotopic map for protein secondary
structure prediction are tested showing a good performance in the
200-240 nm wavelength range that is likely to increase as new protein
structures are known.
