TERMINAL DEOXYRIBONUCLEOTIDYLTRANSFERASE Meaning and Definition

1. Terminal deoxyribonucleotidyltransferase (TdT) is a unique enzyme that belongs to the class of DNA polymerases, specifically the X family. It plays a crucial role in the process of DNA replication and repair. TdT primarily catalyzes the addition of deoxyribonucleotides to the 3' hydroxyl end of a DNA molecule in a template-independent manner, which leads to the extension of DNA chains. This process is commonly known as terminal transferase activity.

   TdT is highly significant in the field of immunology and hematopathology. It is widely expressed in lymphoid tissues, especially during early stages of lymphocyte development. TdT is responsible for the addition of non-templated nucleotides at the junctions of variable (V), diversity (D), and joining (J) gene segments during the rearrangement of antigen receptor genes. This process, known as V(D)J recombination, enhances the diversity of antibodies and T-cell receptors, leading to the development of a robust immune system capable of recognizing a wide range of antigens.

   Furthermore, TdT is also involved in DNA repair mechanisms, such as non-homologous end joining (NHEJ) and DNA double-strand break repair. By adding nucleotides to break points in damaged DNA, TdT assists in the repair process and ensures the stability of the genome.

   In summary, terminal deoxyribonucleotidyltransferase (TdT) is an enzyme that facilitates the addition of deoxyribonucleotides to the ends of DNA molecules, independent of a template. Its role in V(D)J recombination and DNA repair makes it a crucial enzyme in the development and maintenance of the immune system.

Etymology of TERMINAL DEOXYRIBONUCLEOTIDYLTRANSFERASE

The word "Terminal Deoxyribonucleotidyltransferase" has its etymology as follows:

1. Terminal: The word "terminal" is derived from the Latin word "terminus", meaning "boundary" or "end". In the context of biochemistry, it refers to the end or termination point of a molecule or structure.

2. Deoxyribonucleotidyl: The term "deoxyribonucleotidyl" is a combination of several elements.

- "Deoxy" comes from the Greek word "deoxy", which means "without oxygen". In biochemistry, it signifies the absence of an oxygen atom relative to ribonucleotides.

- "Ribo-" is derived from "ribonucleotide", which is a building block of RNA (ribonucleic acid).
