Abstract:
In this report, the frequency of the G-->A transition polymorphism at nucleotide 5557 in exon 39 of the coding sequence of the gene mutated in ataxia-telangiectasia (ATM) was analysed. The frequency of the A and G alleles was estimated in the general population at 0. 15 and 0.85, respectively. This polymorphism can be identified by single-strand conformation polymorphism (SSCP) and by a simple and rapid Dde I digestion after polymerase chain reaction (PCR)-mediated site directed mutagenesis (PSDM).

Allosteric Proteins-ATCase
Aspartate transcarbamoylase (ATCase) is a cytosolic enzyme that catalyzes the condensation of L-aspartate and carbamoyl phosphate to N-carbamoyl-L-aspartate. This reaction is the first step in pyrimidine biosynthesis. UTP and CTP, the end products of the pyrimidine synthesis pathway,...
