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.

Rv0312, (MTCY63.17), len: 620 aa. Conserved hypothetical protein with highly Pro-, Thr-rich C-terminus. Similar to Pro-,Thr-rich region in Rv2264c|AL021925|MTV022_14 from Mycobacterium tuberculosis (592 aa), FASTA scores: opt: 1075, E(): 0, (38.9% identity in 627 aa overlap). Also some similarity with Rv0350|dnaK from Mycobacterium tuberculosis. Possibly membrane protein; has hydrophobic stetch in its middle part.

pirG
Exported repetitive protein precursor PirG (cell surface protein) (EXP53); Surface-exposed protein required for multiplication and intracellular growth; To M.leprae 28 kDa antigen.

ripA
Peptidoglycan hydrolase; Peptidoglycan endopeptidase that cleaves the bond between D- glutamate and meso-diaminopimelate. Binds and degrades high-molecular weight peptidoglycan from a number of Actinobacteria; activity is increased in the presence of RpfB and inhibited by PBP1A (ponA1). Required for normal separation of daughter cells after cell division and for cell wall integrity. Required for host cell invasion and intracellular survival in host macrophages. Belongs to the peptidase C40 family.

Rv2721c
Rv2721c, (MTCY05A6.42c, MTCY154.01c), len: 699 aa. Possible conserved transmembrane ala-, gly-rich protein,equivalent to Q49837|ML1002|U2235I possible conserved membrane protein from Mycobacterium leprae (687 aa), FASTA scores: opt: 2703, E(): 6.6e-135, (60.3% identity in 713 aa overlap). Shows some similaity to Q01377|CSP1 PS1 protein precursor (secreted protein) from Corynebacterium glutamicum (Brevibacterium flavum) (657 aa), FASTA scores: opt: 276, E(): 3.8e-07, (29.4% identity in 272 aa overlap); and Q9KIJ0 Rv2721c-like protein from Mycobacterium paratuberculosis (246 aa), FASTA s [...]

birA
BirA protein; Rv3279c, (MTCY71.19c), len: 266 aa. Possible birA,bifunctional protein: biotin operon repressor and biotin--[acetyl-CoA-carboxylase] synthetase, equivalent to Q9CCL3|BIRA|ML0732 biotin APO-protein ligase from Mycobacterium leprae (274 aa), FASTA scores: opt: 1189,E(): 2.3e-66, (71.2% identity in 271 aa overlap). But as it lacks a BirA h-t-h domain at N-terminus, may simply be biotin apo-protein ligase. Also similar to others e.g. Q9CNX6|BIRA|PM0296 from Pasteurella multocida (312 aa),FASTA scores: opt: 347, E(): 2.7e-14, (32.95% identity in 270 aa overlap); Q9HWC0|BIRA|PA [...]

ripB
Possible invasion protein; Peptidoglycan endopeptidase that cleaves the bond between D- glutamate and meso-diaminopimelate. Binds high-molecular weight peptidoglycan, but does not degrade it.

spmT
Probable exported protein; Catalyzes the cleavage of sphingomyelin, a major lipid in eukaryotic cells, into ceramide and phosphocholine, which are then utilized by M.tuberculosis as carbon, nitrogen and phosphorus sources, respectively. Thus, enables M.tuberculosis to utilize sphingomyelin as a source of several essential nutrients for intracellular growth during infection. Furthermore, lyses erythrocytes and constitutes the main hemolytic factor of M.tuberculosis.
