The routine method for inducing protein function evolution is imitating and speeding protein gene mutation. in this research - amylase gene was mutated in vitro by pcr with dntp in which deoxythymidine triphosphate ( dttp ) was partially replaced by 5 - bromo - 2 ' - deoxyuridine - 5 ' - triphosphate ( 5 - bdu ). the higher the concentration is, the stronger its inducing ability is in a certain range
