Purine ribonucleoside phosphorylase - Names and Identifiers
Purine ribonucleoside phosphorylase - Physico-chemical Properties
| Molecular Formula | C10H12N4O4 |
| Molar Mass | 252.22668 |
| Appearance | White freeze-dried powder. |
| Storage Condition | -20°C |
| MDL | MFCD00131739 |
| Use | It can decompose nucleosides into bases and pentose-1-phosphate, and the reaction is reversible. Purine nucleoside phosphorylase is very important in purine nucleotide remediation anabolism. The lack of purine nucleoside phosphorylase in organisms will lead to damage to T cell function. |

Purine ribonucleoside phosphorylase - Method of use
When measuring the activity, the powder was dissolved in 50mM,PH7.7 potassium phosphate buffer solution. Most of the bacterial PNP is hexamer, the molecular weight of the subunit is 25kDa, the substrate specificity is not strong, and can accept adenosine, guanosine and inosine as substrates; mammals and some microorganisms (Bacillus cereus, Bacillus stearrothmolophushth 6-2)PNP is a trimer, subunit molecular weight of 30~32kDa, usually only accept inosine, guanosine as substrate; Some microorganisms, such as Escherichia coli, bacillus subtilis, Bacillus stearothermophilus, there will be two kinds of polymer PNP.
