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 highly similar to conserved hypothetical proteins from Mycobacterium tuberculosis e.g. Rv3269 (93 aa), FASTA score: (51.1% identity in 94 aa overlap); and Rv1993c (90 aa). (98 aa)
csoRCopper-sensitive operon repressor CsoR; Copper-sensitive repressor that has a key role in copper homeostasis. It is part of the cso operon involved in the cellular response to increasing concentrations of copper inside the bacterium, which can be highly toxic. In the presence of copper, CsoR fully dissociates from the promoter in the cso operon, leading to the transcription of its genes. Binds to a GC-rich pseudopallindromic sequence, 5'-GTAGCCCACCCCCAGTGGGGTGGGA-3', in the cso promoter region. (119 aa)
pafAProteasome accessory factor a PafA; Catalyzes the covalent attachment of the prokaryotic ubiquitin-like protein modifier Pup to the proteasomal substrate proteins, thereby targeting them for proteasomal degradation. This tagging system is termed pupylation. The ligation reaction involves the side-chain carboxylate of the C-terminal glutamate of Pup and the side- chain amino group of a substrate lysine. PafA is required to confer resistance against the lethal effects of reactive nitrogen intermediates (RNI), antimicrobial molecules produced by activated macrophages and other cell types. (452 aa)

Also highly similar to others e.g. CAB96031.1|AL360055 putative metal transporter ATPase from Streptomyces coelicolor (753 aa); NP_241423.1|NC_002570 copper-transporting ATPase from Bacillus halodurans (806 aa); etc. Also highly similar to Z46257|MLACEA_7 aceA gene for isocitrate L from Mycobacterium lepra [...] (752 aa)
mymTMetallothionein, MymT; Metallothioneins are small proteins that have a high content of cysteine residues wich allow them to bind heavy metal ions through clusters of thiolate bonds. MymT binds up to seven ions of Cu(+), with a preference for four to six Cu(+) ions, in a solvent-shielded core. MymT protects M.tuberculosis from copper toxicity. (53 aa)
ricRConserved protein; Under low copper conditions, represses the expression of lpqS, Rv2963, mymT, socA, socB, mmcO and its own expression. In the presence of copper, RicR dissociates from DNA, leading to the expression of the target genes. Members of the RicR regulon are important for copper resistance during infections and full virulence in a mouse model of infection. (96 aa)
mmcOProbable oxidase; Required for copper resistance. In vitro, oxidizes organic substrates and Fe(2+). May act in vivo by oxidation of toxic periplasmic Cu(+); Belongs to the multicopper oxidase family. (504 aa)

Subunits 1-3 form the functional core of the enzyme complex. CO I is the catalytic subunit of the enzyme. Electrons originating in cytochrome c are transferred via the copper A center of subunit 2 and heme A of subunit 1 to the bimetallic center formed by heme A3 and copper B (By similarity). (573 aa)
