3'-O-NH2-2'-dTTP is 3'-O-amino-thymidine-5'-triphosphate: a reversible-terminator dTTP whose 3'-hydroxyl is capped with a small 3'-O-amino group. Key identifiers include CAS 1159990-37-0, molecular formula C10H18N3O14P3, and molecular weight 497.18 (PubChem CID 86760875).

3'-O-modified nucleotides — the 3'-OH capped with a small reversible moiety — are still recognized by DNA polymerase as substrates and act as reversible terminators: incorporation adds one base and stops extension. After each incorporation and readout, the 3'-O-amino cap is removed to regenerate the 3'-OH so the polymerase reinitiates — the basis of cyclic reversible-terminator sequencing-by-synthesis.

Contexto de aplicación

  • Reversible terminator: DNA polymerase incorporates it, adding one thymine and stopping extension for that cycle.
  • Cap removal reinitiates: removing the 3'-O-amino cap regenerates the 3'-OH so synthesis continues — enabling cyclic sequencing-by-synthesis.
  • Thymine building block: supplies the thymine reversible terminator, completing the four-nucleotide (A/C/G/T) 3'-O-amino SBS set.

Preguntas frecuentes

What is a 3'-O-amino reversible terminator?

It is a dNTP whose 3'-hydroxyl is capped with a small 3'-O-amino group. DNA polymerase still incorporates it, but the cap stops further extension after one base. Removing the 3'-O-amino cap regenerates the 3'-OH so synthesis can continue — the principle of cyclic reversible-terminator sequencing-by-synthesis.

Which base does this terminator add?

It is the thymine (T) reversible terminator — 3'-O-amino-thymidine-5'-triphosphate. Together with the A, C, and G 3'-O-amino terminators it forms a four-nucleotide set for sequencing-by-synthesis.
