Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

Also displays efficient peroxynitritase activity, which may help the bacterium to persist in macrophages. Catalyzes the oxidative activation of the antitubercular pro- drug isoniazid (I [...] (740 aa)

lsr2Iron-regulated H-NS-like protein Lsr2; DNA-bridging protein that has both architectural and regulatory roles. Influences the organization of chromatin and gene expression by binding non-specifically to DNA, with a preference for AT-rich sequences, and bridging distant DNA segments. Binds in the minor groove of AT-rich DNA. Represses expression of multiple genes involved in a broad range of cellular processes, including major virulence factors or antibiotic-induced genes, such as iniBAC or efpA , and genes important for adaptation of changing O(2) levels. May also activate expression of [...] (112 aa)
hupBDNA-binding protein HU homolog HupB (histone-like protein) (HLP) (21-kDa laminin-2-binding protein); Histone-like DNA-binding protein which is capable of wrapping DNA to stabilize it, and thus to prevent its denaturation under extreme environmental conditions. Binds DNA non-specifically. Induces lymphoproliferation, particularly in health tuberculin reactors, and is immunogenic. Maybe involved in pathogenesis of inflammatory bowel disease (IBD) in patients with ulcerative colitis and Crohn disease (CD). Bound by anti-neutrophil cytoplasmic antibodies (pANCA), which are a hallmark of IB [...] (214 aa)
espRESX-1 transcriptional regulatory protein EspR; Virulence regulator that has both architectural and regulatory roles. Impacts cell wall functions and pathogenesis through regulation of multiple genes, including the espACD operon, which is a key ESX-1 component. Influences target gene expression positively or negatively, depending on its binding position relative to the genes it controls. Acts by binding directly to the DNA. May play a central role in regulating virulence gene expression. (132 aa)
groEL260 kDa chaperonin 2; Prevents aggregation of substrate proteins and promotes their refolding. (540 aa)
