The gene was then cloned into an expression vector and, following transformation, the resulting bacteria were able to produce quinolinate phosphoribosyl transferase as about 2% of the soluble protein. The enzyme was purified in five steps leading to a homogeneous preparation. The enzyme reaction shows an ordered binding mechanism where the magnesium ion complex of 5-phosphoribosyl-1-pyrophosphate binds first followed by quinolinic acid. The products are pyrophosphate CO2, and nicotinate mononucleotide. Product inhibition studies show that nicotinate mononucleotide is a competitive inhibitor with respect to 5-phosphoribosyl-1-pyrophosphate while pyrophosphate is noncompetitive with respect to both 5-phosphoribosyl-1-pyrophosphate and quinolinic acid. Phthalic acid and fructose-1,6-bisphosphate were used as dead-end inhibitors. Phthalate was competitive with respect to quinolinic acid but uncompetitive with respect to 5-phosphoribosyl-1-pyrophosphate. Fructose-1,6-bisphosphate was a competitive inhibitor with respect to 5-phosphoribosyl-1-pyrophosphate and noncompetitive with respect to quinolinic acid. The Km values for the substrates are 15.6 microM for 5-phosphoribosyl-1-pyrophosphate and 6.4 microM for quinolinic acid."xsd:string |
