Propensity of different mutations. Propensity of 9 different types of mutations generating a helical conformation from the non-redundant database which map into non-helical conformation in the SCOP database. As depicted in Equation 1, propensity here is the ratio of probability of a given type of mutation leading to ambivalent mutated sequences to the probability of the same type of mutation in the total database of mutated sequences.
