Description

Application

Pyrimidine nucleoside phosphorylase (PyNPase) may be used as a marker to predict the malignant potential of breast cancer, especially lymph node metastasis. PyNPase is used to study breast cancer, specifically its role in angiogenesis.

Biochem/physiol Actions

Pyrimidine nucleoside phosphorylase (PyNPase) is a glycosyltransferase that catalyzes the conversion of pyrimidine nucleoside and phosphate to a pyrimidine base and α-D-ribose 1-phosphate. PyNPase plays a significant role in breast cancer angiogenesis.

Unit Definition

One unit will convert 1 μmole each of thymidine and phosphate to thymine and 2-deoxyribose 1-phosphate per minute at pH 7.4 and 25°C
