Mycobacterium tuberculosis originates from a pathogenic bacterial species from the family Mycobacteriaceae. This bacteria is a cause of the disease tuberculosis. Tuberculosis is a lethal, infectious disease that is quite common. Tuberculosis causes symptoms in the lungs and can also cause problems in other parts of the body too. Most symptoms of tuberculosis are asymptomatic, but these infections can eventually progress to an active disease which could kill if activated and untreated. Tuberculosis can infect any part of the body, but it usually infects the lungs (pulmonary tuberculosis) Tuberculosis is spread through the air when people with TB infection cough, sneeze and release pathogenic bacteria into the air. Symptoms of tuberculosis include chronic fever, night sweats, coughing up blood, and weight loss. However, those are just the basic and most common symptoms of tuberculosis. The infection could spread to other parts of the body and thus cause a wide range of symptoms. This disease is classified as a granulomatous inflammatory disease, where grauloma prevents dissemination of the mycobacteria and allows for a local environment for interaction of cells in the immune system. There is a vaccine currently available for tuberculosis called bacillus Calmette-Guerin (BCG), but it is inconsistent in protecting against pulmonary TB. However, since it is effective against disseminated disease in childhood, it is widely used. One negative result of this vaccine is that it causes the tuberculin skin test to come out falsely positive. Treatment for tuberculosis is difficult and long term. It requires adminitsration of multiple antibiotics continuously. A problem in recent years is the ongoing antibiotic resistance in multiple drug-resistant tuberculosis infections.

 * Enzyme Assay information (spectrophotometric, coupled assay ?, reagents):**

Assayed through using the Yamakura te al. (1974) method. Assay mixture contains 200 mM Tris/HCL buffer pH 8, 4 mM of sodium pyruvate, 2 mM i-aspartate semialdehyde, and cell extract. This was then put into incubation at 37°C for 10 min. At the end of this time, the 1 ml assay mixture was mixed with 1 ml 1 M HCl and 1 ml o-aminobenzaldehyde (2 mg ml−1 in ethanol). For another 30 minutes this mixture was incubated in the dark and then finally centrifuged. The supernatant was then used to find absorbance at 540 nm.

-- PDB # or closest PDB entry if using homology model: 1YL5 -- For Homology Model option: N/A Show pairwise alignment of your BLASTP search in NCBI against the PDB: N/A Query Coverage: N/A Max % Identities: N/A % Positives N/A Chain used for homology: N/A [] [] In order to remove unbound proteins, the column was first washed with five column volumes of buffer //A//, then with five column volumes of buffer //B// [20 m//M// Tris pH 8.0, 1 //M// NaCl, 10 m//M// imidazole, 5%(//v/////v//) glycerol, 2 m//M// β-ME] and finally with five column volumes of buffer //C// [20 m//M// Tris pH 8.0, 250 m//M// NaCl, 50 m//M// imidazole, 5%(//v/////v//) glycerol]. The protein was eluted by running a linear gradient from 50 to 800 m//M// imidazole (in buffer //C//). The major peak fractions were pooled and dialyzed against buffer //D// [20 m//M// Tris pH 8.0, 250 m//M// NaCl, 5%(//v/////v//) glycerol]. During overnight dialysis at 277 K, the His tag was cleaved off the protein produced from the pETM-11 construct by adding TEV protease. The cleaved and dialyzed protein solution was passed through a Hi-Trap Chelating HP column pre-equilibrated with buffer //D// and recovered in the flowthrough. []
