Mycobacterium tuberculosis (ATCC 25618 / H37Rv)

Mycobacterium tuberculosis (strain ATCC 25618 / H37Rv) is an obligate pathogenic bacterial species in the family Mycobacteriaceae and the causative agent of tuberculosis (TB). First discovered in 1882 by Robert Koch, M. tuberculosis has an unusual, waxy coating on its cell surface (primarily due to the presence of mycolic acid), which makes the cells impervious to Gram staining. The physiology of M. tuberculosis is highly aerobic and requires high levels of oxygen. It is primarily a pathogen of the mammalian respiratory system and mainly infects the lungs.

An estimated one third of the world population is infected with M. tuberculosis (around 90% in a latent state). TB was responsible for 1.5 million deaths in 2014, with 9.6 million acute cases. TB is considered a leading cause of death worldwide alongside HIV.

The genome of M. tuberculosis was first sequenced in 1998.

Protein models in Repository

From left to right: i) The number of proteins in the reference proteome of Mycobacterium tuberculosis, ii) the number of unique protein sequences for which at least one model is available, iii) the total number of models and iv) a coverage bar plot is shown.
The bar plot shows the coverage for every protein in the reference proteome of Mycobacterium tuberculosis for which there is at least one model. Different colours (dark green to red boxes) represent the coverage of the targets. Targets with high coverage are represented in dark green (more than 80% of the target's length is covered by models), whereas low coverage is shown in red. The size of each box is proportional to the number of target sequences with a given coverage.

Structural Coverage

The plot shows the evolution over years (x-axis) of the fraction of Mycobacterium tuberculosis reference proteome residues (y-axis) for which structural information is available. Different colors (light blue to dark blue) in the plot represent the quality of the sequence alignment between the reference proteome sequences (targets) and the sequences of the proteins in the structure database (templates). Alignments with low sequence identity are displayed in light blue, whereas alignments with high sequence identity are depicted in dark blue. The SWISS-MODEL Template Library is used as database of templates. Only target-template alignments found by HHblits and only residues with atom coordinates are considered.

Residue Coverage

This chart shows the percentage of residues in the Mycobacterium tuberculosis proteome which are covered by experimental structures and the enhancement of coverage by homology modelling by the SWISS-MODEL pipeline. Experimental residue coverage is determined using SIFTS mapping. For residues which are not covered by experimental structures (including where there are no atom records in SIFTS mapping) the model coverage bars are coloured by QMEANDisCo local quality score.

Oligomeric State

Many proteins form oligomeric structures either by self-assembly (homo-oligomeric) or by assembly with other proteins (hetero-oligomeric) to accomplish their function. In SWISS-MODEL Repository, the quaternary structure annotation of the template is used to model the target sequence in its oligomeric form. Currently our method is limited to the modelling of homo-oligomeric assemblies. The oligomeric state of the template is only considered if the interface is conserved.
