thymidine phosphorylase


thy·mi·dine phos·phor·y·lase

phosphorylase that catalyzes the phosphorolysis of thymidine; that is, thymidine and Pi react to form thymine and 2-deoxy-d-ribose 1-phosphate.

TYMP

A gene on chromosome 22q13.33 that encodes thymidine phosphorylase, which specifically acts on endothelial cells and promotes angiogenesis.
Molecular pathology
Defects in TYMP cause mitochondrial neurogastrointestinal encephalomyopathy.
