Does anybody know of a program to give a quick estimate of the total volume of a protein from sequence ? Not really going into the folding problem, just trying to get a relative mesure of protein size. The fast way to do it would be just to sum up atom volumes but I'm sure there must be something allready done on this. Thanx -- Adira já ao Net Dialup Light. Acesso profissional gratuito.
