The 3'to 5'can only remove one mononucleotide at a time, and the 5'to 3'activity can remove mononucleotides or up to 10 nucleotides at a time.
22.
Both the neuronal and the macrophage forms are unusual among oxidative enzymes in requiring several electron donors : flavin adenine dinucleotide ( FAD ), flavin mononucleotide ( FMN ), NADPH, and tetrahydrobiopterin.
23.
Mutations in the hMSH6 gene cause the protein to be nonfunctional or only partially active, thus reducing its ability to repair mistakes in DNA . The loss of MSH6 function results in instability at mononucleotide repeats.
24.
Third, it may be caused by excess leucine, as it inhibits quinolinate phosphoribosyl transferase ( QPRT ) and inhibits the formation of Niacin or Nicotinic acid to Nicotinamide mononucleotide ( NMN ) causing pellegra like symptoms to occur.
25.
Between the strand-biased microsatellite repeats and G : C mononucleotide repeats, all sequence variations retained one or two base pairs with A ( purine ) interrupting the pyrimidine-rich strand and T ( pyrimidine ) interrupting the purine-rich strand.
26.
The "'FMN riboswitch "'( also known as "'RFN element "') is a highly conserved 5'- untranslated regions of prokaryotic mRNAs that encode for flavin mononucleotide ( FMN ) biosynthesis and transport proteins.
27.
NMNAT ( EC 2.7 . 7.1 ) is a central enzyme in NAD biosynthesis, catalyzing the condensation of nicotinamide mononucleotide ( NMN ) or nicotinic acid mononucleotide ( NaMN ) with the AMP moiety of ATP to form NAD or NaAD.

29.
Each nucleotide is made of an acyclic nitrogenous base, a pentose and one to three cellular signaling ( cyclic guanosine monophosphate and cyclic adenosine monophosphate ), and are incorporated into important cofactors of enzymatic reactions ( coenzyme A, flavin adenine dinucleotide, flavin mononucleotide, and nicotinamide adenine dinucleotide phosphate ).
30.
One with a gene coding for nicotinic acid mononucleotide adenylyltransferase upstream and a gene coding for a molybdenum ABC transporter downstream, which is shared by the third copy of ar14 family in the " A . radiobacter " genome ( Arr14CI3 ) and in the Rhizobium group genomes ( ReCFNr14C3, Rlt1325r14C3, Rlvr14C3, Rlt2304r14C3 ).
