Description
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.
Abbr
PyNPase, Recombinant
Applications
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.
