  The main objective of the paper is to find the motif information.The
functionalities of the proteins are ideally found from their motif information
which is extracted using various techniques like clustering with k-means,
hybrid k-means, self-organising maps, etc., in the literature. In this work
protein sequence information is extracted using optimised k-means algorithm.
The particle swarm optimisation technique is one of the frequently used
optimisation method. In the current work the PSO k-means is used for motif
information extraction. This paper also deals with the comparison between the
motif information obtained from clusters and biclustersusing PSO k-means
algorithm. The motif information acquired is based on the structure homogeneity
of the protein sequence.
