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.
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.
Other Notes
One unit will convert 1 μmole each of 2′-deoxyuridine and phosphate to uracil and 2-deoxyribose 1-phosphate per minute at pH 7.4 and 37 °C.

Pyrimidine nucleoside phosphorylase (PYNP) catalyzes the reversible phosphorolysis of pyrimidines in the nucleotide synthesis salvage pathway. We have built a model of a closed active conformation of the three-dimensional structure of PYNP from Bacillus subtilis. Using docking, molecular dynamics, and

Genome comparison permits identification of chromosome regions conserved during evolution. Bacillus subtilis and Escherichia coli are so distant that there exists very few conserved landmarks in their genome organisation. Analysis of the conserved cmk rpsA cluster pinpointed the importance of

Pyrimidine nucleoside phosphorylase (PYNP) catalyzes the reversible phosphorolysis of pyrimidines in the nucleotide synthesis salvage pathway. In lower organisms (e.g. Bacillus stearothermophilus) PYNP accepts both thymidine and uridine, whereas in mammalian and other higher organisms it is specific for thymidine
