Pyrimidine nucléoside Phosphorylase de Bacillus subtilis, recombinant, exprimé en E. coli, >=70 unités/mg de protéines

Non disponible en dehors du Royaume-Uni et de l'Irlande

Biochem/physiol Actions

Pyrimidine nucleoside phosphorylase functions in the nucleotide synthesis salvage pathway by catalyzing the reversible phosphorolysis of pyrimidines. Both uridine and thymidine are substrates.

General description

The roles of the residues in the catalytic active site of pyrimidine nucleoside phosphorylase from Bacillis subtilis have been elucidated using hybrid quantum-mechanical/molecular-mechanical methods.

Packaging
