The Mycobacterium tuberculosis complex (MTC or MTBC) is a genetically related group of Mycobacterium species that can cause tuberculosis in humans or other animals. It includes: Mycobacterium tuberculosis; Mycobacterium africanum; Mycobacterium orygis [1] Mycobacterium bovis and the Bacillus Calmette–Guérin strain; Mycobacterium microti ...
As of June 2006, 82 TB protein structures have been determined, 15 since January 1, 2006. The database of linked structural and functional information that has been constructed using this information can form a lasting basis for understanding M. tuberculosis pathogenesis and for structure-based drug design.

M. tuberculosis is able to reproduce inside the macrophage and will eventually kill the immune cell. The primary site of infection in the lungs, known as the Ghon focus, is generally located in either the upper part of the lower lobe, or the lower part of the upper lobe. [13] Tuberculosis of the lungs may also occur via infection from the blood ...
The nature of the host-pathogen interaction between humans and M. tuberculosis is considered to have a genetic component. A group of rare disorders called Mendelian Susceptibility to Mycobacterial Diseases (MSMD) was observed in a subset of individuals with a genetic defect that results in increased susceptibility to Mycobacterial infection.
The human TBR1 gene is located on the q arm of the positive strand of chromosome 2. It is 8,954 base pairs in length. [5] TBR1 is one of the three genes that make up the TBR1 subfamily of T-box genes. The two other genes that form the TBR1 subfamily are EOMES (also known as TBR2) and TBX21 (also known as T-BET).
Symptoms of M. tuberculosis include coughing that lasts for more than three weeks, hemoptysis, chest pain when breathing or coughing, weight loss, fatigue, fever, night sweats, chills, and loss of appetite. M. tuberculosis also has the potential of spreading to other parts of the body. This can cause blood in urine if the kidneys are affected ...
Cord factor, or trehalose dimycolate (TDM), is a glycolipid molecule found in the cell wall of Mycobacterium tuberculosis and similar species. It is the primary lipid found on the exterior of M. tuberculosis cells. [1] Cord factor influences the arrangement of M. tuberculosis cells into long and slender formations, giving its name. [2]
In eukaryotes, the TATA box is located 25 base pairs upstream of the start site that Rpb4/Rbp7 use to initiate transcription. In metazoans, the TATA box is located 30 base pairs upstream of the transcription start site. [5] While in yeast, S. cerevisiae, the TATA box has a variable position which can range from 40 to 100 bp upstream of the ...
