Showing metabocard for Uridine triphosphate (HMDB0000285)

General function:

Involved in hydrolase activity

Specific function:

In the nervous system, could hydrolyze ATP and other nucleotides to regulate purinergic neurotransmission. Could also be implicated in the prevention of platelet aggregation by hydrolyzing platelet-activating ADP to AMP. Hydrolyzes ATP and ADP equally well.

Gene Name:

ENTPD1

Uniprot ID:

P49961

Molecular weight:

58706.0

Reactions

General function:

Involved in calcium ion binding

Specific function:

Calcium-dependent nucleotidase with a preference for UDP. The order of activity with different substrates is UDP > GDP > UTP > GTP. Has very low activity towards ADP and even lower activity towards ATP. Does not hydrolyze AMP and GMP. Involved in proteoglycan synthesis.

Possesses nucleoside-diphosphate kinase, serine/threonine-specific protein kinase, geranyl and farnesyl pyrophosphate kinase, histidine protein kinase and 3'-5' exonuclease activities. Involved in cell proliferation, differentiation and development, signal transduction, G protein-coupled receptor endocytosis, and gene expression. Required for neural development including neural patterning and cell fate determination.

Gene Name:

NME1

Uniprot ID:

P15531

Molecular weight:

17148.635

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.
