STRINGSTRING
STRING protein interaction network
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

hemNHeme chaperone HemW; Probably acts as a heme chaperone, transferring heme to an unknown acceptor. Binds one molecule of heme per monomer, possibly covalently (By similarity). Binds 1 [4Fe-4S] cluster. The cluster is coordinated with 3 cysteines and an exchangeable S-adenosyl-L- methionine (By similarity); Belongs to the anaerobic coproporphyrinogen-III oxidase family. HemW subfamily. (375 aa)    
Predicted Functional Partners:
Rv2390c
Rv2390c, (MTCY253.31), len: 185 aa. Conserved hypothetical protein, similar to other Mycobacterium tuberculosis proteins Q11032|YD62_MYCTU|MTCY02B10.26c|Rv1362c hypothetical 23.5 kDa protein (220 aa), FASTA scores: opt: 223, E(): 2.1e-07,(27.4% identity in 190 aa overlap); and Q11033|YD63_MYCTU|MTCY02B10.27c|Rv1363c hypothetical 28.3 kDa protein (261 aa), FASTA scores: opt: 238, E(): 2.7e-08,(27.6% identity in 163 aa overlap).

rpfD
Probable resuscitation-promoting factor RpfD; Factor that stimulates resuscitation of dormant cells. Has peptidoglycan (PG) hydrolytic activity. Active in the pM concentration range. Has little to no effect on actively-growing cells. PG fragments could either directly activate the resuscitation pathway of dormant bacteria or serve as a substrate for endogenous Rpf, resulting in low molecular weight products with resuscitation activity. Belongs to the transglycosylase family. Rpf subfamily.

gltB
Glutamate synthase [NADPH] large chain; Rv3859c, (MTCY01A6.09), len: 1527 aa. Probable gltB,ferredoxin-dependent glutamate synthase large subunit,equivalent to Q9CDD5|GLTB|ML0061 putative ferredoxin-dependent glutamate synthase from Mycobacterium leprae (1527 aa), FASTA scores: opt: 9277, E(): 0, (90.25% identity in 1527 aa overlap). Also highly similar to many e.g. Q9S2Y9|SC3A3.04c from Streptomyces coelicolor (1514 aa), FASTA scores: opt: 5939, E(): 0, (64.3% identity in 1544 aa overlap); Q9Z465|GLTB from Corynebacterium glutamicum (Brevibacterium flavum) (1510 aa), FASTA scores: opt [...]

mhuD
Possible heme degrading protein MhuD; Catalyzes the oxidative degradation of the heme macrocyclic porphyrin ring in the presence of a suitable electron donor such as ascorbate or NADPH--cytochrome P450 reductase, with subsequent release of free iron.
  
  
 0.663
hemE
Probable uroporphyrinogen decarboxylase HemE (uroporphyrinogen III decarboxylase) (URO-D) (UPD); Catalyzes the decarboxylation of four acetate groups of uroporphyrinogen-III to yield coproporphyrinogen-III.

Rv3050c
Rv3050c, (MTV012.65c), len: 246 aa. Probable transcriptional regulatory protein TetR-family, equivalent but shorter to Q9CBQ1|ML1733 from Mycobacterium leprae (275 aa), FASTA scores: opt: 1381,(E): 2.7e-79, (86.25% identity in 240 aa overlap); AAK44712|MT0489 from Mycobacterium tuberculosis strain CDC1551 (256 aa), FASTA scores: opt: 328,(E): 1.8e-13, (30.75% identity in 234 aa overlap); etc. Also some similarity to O53757|Rv0472c|MTV038.16c. Alternative starts possible at 68052 or 67923. Has potential helix-turn-helix motif at positons 51-72.
