Abstract—Research in Protein Interactions has revealed that works can be considered as either Random
these interactions can be considered in the form of work works or as Scale works. In works the
that there exists proteins with various degrees of connectivity in connections between the nodes are assumed to follow a
work. In this paper a set of proteins sequences are treated Poisson distribution where as in the case of Scale Free
as a system of linear equations to see whether there exist any
Networks it follows a Power Law distribution [4]. One of the
relation between the degree of connectivity and the amino acid
frequencies of protein sequences. The application of this method properties of Power Law distribution is that only a few nodes
on a set of functional proteins revealed that there exists such a have high degree of connectivity. Currently there is no
relation. Moreover this method paves a way to identify highly consensus on the threshold value which determines whether a
connected (hub) pro
