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

Probable conserved integral membrane protein, Mer family possibly involved in transport of mercury, similar to others, and to the fourth protein of the mercury resistance operon of Streptomyces sp (or other organisms), and to putative cytochrome-c biogenesis proteins e.g. Q9XBD1|CZA382.20C putative integral membrane transporter from Amycolatopsis orientalis (298 aa), FASTA scores: opt: 913, E(): 7.6e-46,(51.55% identity in 293 aa overlap); P30344|MER4_STRLI mercury resistance probable HG transport protein from Streptomyces lividans (319 aa), FASTA s [...] (287 aa)    
Predicted Functional Partners:
mpt53
Soluble secreted antigen Mpt53 precursor; Disulfide oxidoreductase that catalyzes the oxidation of reduced, unfolded secreted proteins to form disulfide bonds. Despite a weak homology to thioredoxin this cannot serve as a substrate for thioredoxin reductase.

dipZ
Rv2874, (MT2942, MTCY274.05), len: 695 aa. Possible dipZ, cytochrome c-type biogenesis protein (see citation below), probable integral membrane protein, similar in part to others or hypothetical proteins e.g. CAC48606|SMB20213 conserved hypothetical protein from Rhizobium meliloti (Sinorhizobium meliloti) (627 aa), FASTA scores: opt: 844,E(): 7.3e-43, (32.65% identity in 643 aa overlap); Q9ZMH0|CCDA or JHP0250 putative cytochrome C-type biogenesis protein from Helicobacter pylori J99 (Campylobacter pylori J99) (239 aa), FASTA scores: opt: 250, E(): 1.4e-07, (27.3% identity in 227 aa ov [...]

ahpE
Probable peroxiredoxin AhpE; Thiol-specific peroxidase that catalyzes the reduction of hydrogen peroxide and organic hydroperoxides to water and alcohols, respectively. Plays a role in cell protection against oxidative stress by detoxifying peroxides. May represent an important antioxidant defense against cytotoxic peroxides, especially peroxynitrite, which can be formed by activated macrophages during infection. Belongs to the peroxiredoxin family. AhpE subfamily.

frr
Ribosome recycling factor Frr (ribosome releasing factor) (RRF); Responsible for the release of ribosomes from messenger RNA at the termination of protein biosynthesis. May increase the efficiency of translation by recycling ribosomes from one round of translation to another; Belongs to the RRF family.

sigL
Probable alternative RNA polymerase sigma factor SigL; 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 by regulated intramembrane proteolysis. Over-expression of SigL induces 19-28 genes including polyketide synthases, secreted and membrane proteins. Might play a minor role in regulating SigB.
