dUDP (PAMDB000221)

General function:

Involved in oxidation-reduction process

Specific function:

Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides. R1 contains the binding sites for both substrates and allosteric effectors and carries out the actual reduction of the ribonucleotide. It also provides redox- active cysteines

Gene Name:

nrdA

Locus Tag:

PA1156

Molecular weight:

107.1 kDa

Reactions

General function:

Involved in thymidylate kinase activity

Specific function:

Catalyzes the reversible phosphorylation of deoxythymidine monophosphate (dTMP) to deoxythymidine diphosphate (dTDP), using ATP as its preferred phosphoryl donor. Situated at the junction of both de novo and salvage pathways of deoxythymidine triphosphate (dTTP) synthesis, is essential for DNA synthesis and cellular growth

Gene Name:

tmk

Locus Tag:

PA2962

Molecular weight:

23.1 kDa

Reactions

General function:

Involved in nucleoside diphosphate kinase activity

Specific function:

Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate
