Enzyme Information

2.7.4.22
UMP kinase.
based on mapping to UniProt P43890
ATP + UMP = ADP + UDP.
-!- Strictly specific for UMP as substrate and is used by prokaryotes in the de novo synthesis of pyrimidines, in contrast to eukaryotes, which use the dual-specificity enzyme EC 2.7.4.14 for the same purpose. -!- Subject of feedback regulation, being inhibited by UTP and activated by GTP.
