Prokaryotic and Eukaryotic Non-membrane Proteins have Biased Amino Acid Distribution

Abstract

Proteins constitute the important constituent of the cellular machinery. The comparative analysis of non-membrane proteins (nMPs) between prokaryotes and eukaryotes carried out to determine the biasedness in amino acid distribution. On comparison, the results revealed that ‘Ala’ is the dominant amino acid in prokaryotic nMPs while ‘Lys, Ser and Cys’ are the dominant amino acids in eukaryotic nMPs.
