Archaebacteria is known for its presence in varied extreme environments, suggesting potential applications and an on-going need study its diversity. This led to increasing emphasis on archaeal genomic and proteomic studies. However, there is no work to-date examining the overall proteomic diversity in archaebacteria. In this study, we examine the proteomic diversities among 19 sequenced archaebacterial species and found significant differences (p-value < 2 x 10-43) in average peptide lengths, isoelectric points, aromaticity, instability, and hydropathy. Majority of the peptides in each species are stable. Predominantly consistent correlations, though widely varied, were observed between peptide physical properties except between peptide length and hydropathy. This study provides a cursory view highlighting the diversity of archaeal proteomes; thus, re-iterating the call for further studies into these organisms.
