THYMIDINE PHOSPHORYLASE Meaning and
Definition
-
Thymidine phosphorylase is an enzyme that plays a crucial role in the metabolism of nucleotides, specifically thymidine. It is primarily found in the cytoplasm of cells and is involved in the conversion of thymidine to thymine and 2-deoxy-D-ribose-1-phosphate.
Thymidine phosphorylase is classified as a pyrimidine nucleoside phosphorylase, belonging to the family of glycosyltransferases. Its main function is to catalyze the cleavage of the glycosidic bond between thymidine and phosphate, resulting in the release of thymine and the sugar 2-deoxy-D-ribose-1-phosphate. This reaction is a critical step in the breakdown of thymidine, which serves as a precursor for DNA synthesis.
Apart from its role in nucleotide metabolism, thymidine phosphorylase is also known to have angiogenic properties. It has been found to promote the formation of new blood vessels by stimulating the migration and proliferation of endothelial cells, which are the building blocks of blood vessels. This has led to its identification as a potential therapeutic target for disorders associated with aberrant angiogenesis, such as cancer.
In summary, thymidine phosphorylase is an enzyme involved in the metabolism of thymidine, playing a key role in its breakdown to thymine and 2-deoxy-D-ribose-1-phosphate. It also exhibits angiogenic properties, making it a target for therapeutic interventions in pathological conditions characterized by abnormal blood vessel formation.

Etymology of THYMIDINE PHOSPHORYLASE
The word "thymidine" comes from the nucleoside "thymine", which is one of the four bases found in DNA. Thymine's name is derived from the plant thyme, from which it was originally isolated.
The word "phosphorylase" is derived from the term "phosphorylation", which refers to the addition of a phosphate group to a molecule. In this case, it indicates the enzyme's ability to transfer a phosphate group.
Therefore, "thymidine phosphorylase" refers to an enzyme that is capable of transferring a phosphate group to thymidine.
