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
Your Input:
ompAOuter membrane protein A (3a;II*;G;d); With TolR probably plays a role in maintaining the position of the peptidoglycan cell wall in the periplasm (Probable). Plays a role in resistance to environmental stress, and a role in outer membrane functionality and cell shape. Non-covalently binds peptidoglycan (Probable). Acts as a porin with low permeability that allows slow penetration of small solutes. A very abundant protein, there can be up to 210,000 OmpA molecules per cell. Reconstitution in unilamellar lipid vesicles shows only about 3% of the protein is in an open conformation, whic [...] (346 aa)
rpoARNA polymerase, alpha subunit; DNA-dependent RNA polymerase (RNAP) catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. This subunit plays an important role in subunit assembly since its dimerization is the first step in the sequential assembly of subunits to form the holoenzyme. (329 aa)
lppMurein lipoprotein; An outer membrane lipoprotein that controls the distance between the inner and outer membranes; adding residues to Lpp increases the width of the periplasm. The only protein known to be covalently linked to the peptidoglycan network (PGN). Also non-covalently binds the PGN. The link between the cell outer membrane and PGN contributes to the maintenance of the structural and functional integrity of the cell envelope, and maintains the correct distance between the PGN and the outer membrane. The most adundant cellular protein, there can be up to 10(6) Lpp molecules pe [...] (78 aa)
tolBPeriplasmic protein; Part of the Tol-Pal system, which plays a role in outer membrane invagination during cell division and is important for maintaining outer membrane integrity. TolB occupies a key intermediary position in the Tol-Pal system because it communicates directly with both membrane-embedded components, Pal in the outer membrane and TolA in the inner membrane. Is also involved in the uptake of some colicins A. The Tol-Pal system is also required for polar localization of chemoreceptors clusters. (430 aa)
mlaBABC transporter maintaining OM lipid asymmetry, cytoplasmic STAS component; Part of the ABC transporter complex MlaFEDB, which is involved in a phospholipid transport pathway that maintains lipid asymmetry in the outer membrane by retrograde trafficking of phospholipids from the outer membrane to the inner membrane. MlaB plays critical roles in both the assembly and activity of the complex. May act by modulating MlaF structure and stability. (97 aa)
mlaCABC transporter maintaining OM lipid asymmetry, periplasmic binding protein; Involved in a phospholipid transport pathway that maintains lipid asymmetry in the outer membrane by retrograde trafficking of phospholipids from the outer membrane to the inner membrane. May transfer phospholipid across the periplasmic space and deliver it to the MlaFEDB complex at the inner membrane. Belongs to the MlaC/ttg2D family. (211 aa)
mlaAABC transporter maintaining OM lipid asymmetry, OM lipoprotein component; Involved in a phospholipid transport pathway that maintains lipid asymmetry in the outer membrane by retrograde trafficking of phospholipids from the outer membrane to the inner membrane. Belongs to the MlaA family. (251 aa)
palPeptidoglycan-associated outer membrane lipoprotein; Part of the Tol-Pal system, which plays a role in outer membrane invagination during cell division and is important for maintaining outer membrane integrity. The Tol-Pal system is also required for polar localization of chemoreceptors clusters. (173 aa)
