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

rsfAAnti-anti-sigma factor RsfA (anti-sigma factor antagonist) (regulator of sigma F A); Positive, redox-sensitive regulator of sigma-F (SigF) activity. When reduced binds to anti-sigma-F factor RsbW (UsfX) preventing its binding to SigF, thus activating transcription. Belongs to the anti-sigma-factor antagonist family. (128 aa)    
Predicted Functional Partners:
Rv1364c
Rv1364c, (MTCY02B10.28c), len: 653 aa. Possible sigma factor regulatory protein, some similarity to RSBU_BACSU|P40399 sigma factor sibg regulation protein from Bacillus subtilis (335 aa), FASTA scores: opt: 224, E(): 2e-07, (25.8% identity in 244 aa overlap). Also known as mursiF.
 
 
 0.998
rsbW
Anti-sigma factor RsbW (sigma negative effector); A cognate anti-sigma factor for alternative sigma factor SigF. Alternative sigma factors are held in an inactive form by an anti-sigma factor. Binds ATP and GTP, may hydrolyze both.
 
 
 0.952
rsfB
Anti-anti-sigma factor RsfB (anti-sigma factor antagonist) (regulator of sigma F B); Positive regulator of sigma-F (SigF) activity. Binds to anti- sigma-F factor RsbW (UsfX) preventing its binding to SigF, thus activating transcription.

Rv1366
Hypothetical protein; Rv1366, (MTCY02B10.30), len: 273 aa. Hypothetical unknown protein.
 
  
 0.829
Rv1354c
Conserved hypothetical protein; Rv1354c, (MTCY02B10.18c), len: 623 aa. Conserved hypothetical protein, similar to many hypothetical proteins e.g. the C-terminus of G1001455 Synechocystis sp. (1244 aa), FASTA scores: opt: 933, E(): 0, (36.8% identity in 462 aa overlap); also similar to Rv1357c|MTCY02B10.21c (34.0% identity in 253 aa overlap).

obg
Probable GTP1/Obg-family GTP-binding protein Obg; An essential GTPase which binds GTP, GDP and possibly (p)ppGpp with moderate affinity, with high nucleotide exchange rates and a fairly low GTP hydrolysis rate. Plays a role in control of the cell cycle, stress response, ribosome biogenesis and in those bacteria that undergo differentiation, in morphogenesis control (By similarity). GTPase activity is not inhibited by ATP or GDP. Overexpression decreases cell growth starting in late log phase and continuing into stationary phase ; Belongs to the TRAFAC class OBG-HflX-like GTPase superfa [...]

fbiC
Probable F420 biosynthesis protein FbiC; Catalyzes the radical-mediated synthesis of 7,8-didemethyl-8- hydroxy-5-deazariboflavin (FO) from 5-amino-6-(D-ribitylamino)uracil and L-tyrosine; In the C-terminal section; belongs to the radical SAM superfamily. CofH family.
  
    0.658
Rv1359
Rv1359, (MTCY02B10.23), len: 250 aa. Probable transcriptional regulatory protein, similar to Rv0891c|MTCY31.19c, (48.5% identity in 204 aa overlap) and to Rv1358|MTCY02B10.22 (43.7% identity in 197 aa overlap); To class-3 of adenylyl cyclases.
