Bacterial UMP kinases are essential enzymes involved in the multistep synthesis of nucleoside triphosphates. They are hexamers regulated by the allosteric activator GTP and inhibited by UTP. We solved the crystal structure of Escherichia coli UMP kin

Bacterial UMP kinases are essential enzymes involved in the multistep synthesis of UTP. They are hexamers regulated by GTP (allosteric activator) and UTP (inhibitor). We describe here the 2.8 angstroms crystal structure of Escherichia coli UMP kinase

In this work, we examined the regulation by GTP and UTP of the UMP kinases from eight bacterial species. The enzyme from Gram-positive organisms exhibited cooperative kinetics with ATP as substrate. GTP decreased this cooperativity and increased the

Guanosine monophosphate kinases (GMPKs), which catalyze the phosphorylation of GMP and dGMP to their diphosphate form, have been characterized as monomeric enzymes in eukaryotes and prokaryotes. Here, we report that GMPK from Escherichia coli (ecGMPK

Bacterial uridine monophosphate (UMP) kinases are essential enzymes encoded bypyrHgenes, and conditional-lethal or otherpyrHmutants were analysed with respect to structure–function relationships. A set of thermosensitivepyrHmutants fromEscherichia

DNA unwinding at eukaryotic replication forks displaces parental histones, which must be redeposited onto nascent DNA in order to preserve chromatin structure. By screening systematically for replisome components that pick up histones released from c

To initiate DNA replication, cells first load an MCM helicase double hexamer at origins in a reaction requiring ORC, Cdc6, and Cdt1, also called pre-replicative complex (pre-RC) assembly. The essential mechanistic role of Cdc6 ATP hydrolysis in this
