General function:
Involved in hydrolase activity
Specific function:
Catalyzes the hydrolysis of phosphoanhydride bonds of nucleoside tri- and di-phosphates.

Reactions
Protein Details
21. Ribonucleoside-diphosphate reductase small chain 2
General function:
Involved in oxidoreductase activity
Specific function:
Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides. RNR4 is required for proper folding of RNR2 and assembly with the large subunits
Gene Name:
RNR4
Uniprot ID:
P49723
Molecular weight:
40054.19922
Reactions
2'-deoxyribonucleoside diphosphate + thioredoxin disulfide + H(2)O → ribonucleoside diphosphate + thioredoxin.
Protein Details
22. Guanosine-diphosphatase
General function:
Involved in hydrolase activity
Specific function:
After transfer of sugars to endogenous macromolecular acceptors, the enzyme converts nucleoside diphosphates to nucleoside monophosphates which in turn exit the Golgi lumen in a coupled antiporter reaction, allowing entry of additional nucleotide sugar from the cytosol
Gene Name:
GDA1
Uniprot ID:
P32621
Molecular weight:
56821.0
Reactions
GDP + H(2)O → GMP + phosphate.
