Accepted name: thymidine phosphorylase
Reaction: thymidine + phosphate = thymine + 2-deoxy-α-D-ribose 1-phosphate
Other name(s): pyrimidine phosphorylase; thymidine-orthophosphate deoxyribosyltransferase; animal growth regulators, blood platelet-derived endothelial cell growth factors; blood platelet-derived endothelial cell growth factor; deoxythymidine phosphorylase; gliostatins; pyrimidine deoxynucleoside phosphorylase; thymidine:phosphate deoxy-D-ribosyltransferase
Systematic name: thymidine:phosphate deoxy-α-D-ribosyltransferase
Comments: The enzyme in some tissues also catalyses deoxyribosyltransferase reactions of the type catalysed by EC, nucleoside deoxyribosyltransferase.
