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

rseAAnti-sigma factor RseA; An anti-sigma factor for extracytoplasmic function (ECF) sigma factor SigE. ECF sigma factors are held in an inactive form by an anti-sigma factor; Belongs to the zinc-associated anti-sigma factor (ZAS) superfamily. (154 aa)    
Predicted Functional Partners:
Rv3222c
Rv3222c, (MTCY07D11.04), len: 183 aa. Hypothetical protein, with some similarity to Q9SZD2|F19B15.50|AT4G29020 glycine-rich protein like from Arabidopsis thaliana (Mouse-ear cress) (158 aa), FASTA scores: opt: 131, E(): 0.77, (33.35% identity in 126 aa overlap); Q9S222|SCI51.18 putative transcriptional regulator from Streptomyces coelicolor (548 aa), FASTA scores: opt: 133, E(): 1.6,(36.25% identity in 149 aa overlap); etc. Also some similarity to other hypothetical Mycobacterium tuberculosis proteins e.g. O06292|Rv0341|MTCY13E10.01 (479 aa), FASTA scores: opt: 141, E(): 0.5, (31.2% id [...]

sigE
Alternative RNA polymerase sigma factor SigE; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Extracytoplasmic function (ECF) sigma factors are held in an inactive form by an anti-sigma factor until released. Responds to heat shock and surface stress (detergent exposure). When combined with isolated core RNA polymerase from M.smegmatis is able to guide initiation from the sigB promoter. Required for full expression of sigB, and for sigB induction after detergent exposure but not after heat shock. Con [...]

Rv0093c
Rv0093c, (MTCY251.12c), len: 282 aa. Probable conserved membrane protein, equivalent only to CAC30943.1|AL583924 probable integral membrane protein from Mycobacterium leprae (237 aa). A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al.,2004).
 
  
 0.844
tatB
Probable protein TatB; Part of the twin-arginine translocation (Tat) system that transports large folded proteins containing a characteristic twin- arginine motif in their signal peptide across membranes. Together with TatC, TatB is part of a receptor directly interacting with Tat signal peptides. TatB may form an oligomeric binding site that transiently accommodates folded Tat precursor proteins before their translocation.
 
    0.804
clpC1
Probable ATP-dependent protease ATP-binding subunit ClpC1; ATP-dependent specificity component of the Clp protease. It directs the protease to specific substrates. Can perform chaperone functions in the absence of ClpP (By similarity). Degrades anti-sigma-E factor RseA in the presence of ClpP2.

htrA
Rv1223, (MTCI61.06), len: 528 aa. Probable htrA (alternate gene name: degP), serine protease precursor (see citations below), equivalent to U15180|MLU15180_31|Q49972|ML1078|HTRA possible serine protease from Mycobacterium leprae (533 aa), FASTA scores: opt: 2777, E(): 4.1e-141, (81.6% identity in 533 aa overlap). Also similar to many others e.g. HTRA_ECOLI|P09376 protease do precursor from Escherichia coli (474 aa), FASTA scores: opt: 581, E(): 9.1e-27, (36.3% identity in 278 aa overlap); etc. Contains PS00017 ATP/GTP-binding site motif A (P-loop).

rsdA
Unknown alanine and proline rich protein; An anti-sigma factor for extracytoplasmic function (ECF) sigma factor SigD. ECF sigma factors are held in an inactive form by an anti-sigma factor until released by regulated intramembrane proteolysis (RIP). RIP occurs when an extracytoplasmic signal triggers a concerted proteolytic cascade to transmit information and elicit cellular responses. The membrane-spanning regulatory substrate protein is first cut extracytoplasmically (site-1 protease, S1P), then within the membrane itself (site-2 protease, S2P), while cytoplasmic proteases finish deg [...]
