What Might be the Difference in Viral Proteins?

The difference between normal and viral proteins is the way the amino acids organized in someform. Though both proteins use same 20 naturally occurring amino acids, it differs in arrangements. Thisdifference cannot be felt by merely comparing the amino acid sequence but at atom level. This is analysedand compared in terms of carbon distribution as carbon is the only element that contributes towards thedominant force, hydrophobic interaction. For this purpose the arenaviruses have been selected here forstudy. The protein sequences of 7 arenaviruses are analysed. Our results show that the carbon distributionin viral proteins is different from the normal proteins. Either the carbon content is different or the distributionis not uniform. This carbon distribution analysis uses our earlier report of 31.44% of carbon for its structureand activity.
