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.

ftsYPutative low affinity ammonium uptake protein (pseudogene); Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Acts as a receptor for the complex formed by the signal recognition particle (SRP) and the ribosome-nascent chain (RNC). (495 aa)    
Predicted Functional Partners:
ffh
Signal recognition particle protein; Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Binds to the hydrophobic signal sequence of the ribosome-nascent chain (RNC) as it emerges from the ribosomes. The SRP-RNC complex is then targeted to the cytoplasmic membrane where it interacts with the SRP receptor FtsY. Belongs to the GTP-binding SRP family. SRP54 subfamily.

secE
Putative translocase protein; Essential subunit of the Sec protein translocation channel SecYEG. Clamps together the 2 halves of SecY. May contact the channel plug during translocation.
    
 0.988
secG
Protein transport/translocation membrane protein; Involved in protein export. Participates in an early event of protein translocation; Belongs to the SecG family.
   
 0.987
secA
Translocase protein; Part of the Sec protein translocase complex. Interacts with the SecYEG preprotein conducting channel. Has a central role in coupling the hydrolysis of ATP to the transfer of proteins into and across the cell membrane, serving as an ATP-driven molecular motor driving the stepwise translocation of polypeptide chains across the membrane.
     
 0.986
secY
Preprotein translocase SecY subunit; The central subunit of the protein translocation channel SecYEG. Consists of two halves formed by TMs 1-5 and 6-10. These two domains form a lateral gate at the front which open onto the bilayer between TMs 2 and 7, and are clamped together by SecE at the back. The channel is closed by both a pore ring composed of hydrophobic SecY resides and a short helix (helix 2A) on the extracellular side of the membrane which forms a plug. The plug probably moves laterally to allow the channel to open. The ring and the pore may move independently.

secA2
Putative preprotein translocase; Part of the Sec protein translocase complex. Interacts with the SecYEG preprotein conducting channel. Has a central role in coupling the hydrolysis of ATP to the transfer of proteins into and across the cell membrane, serving as an ATP-driven molecular motor driving the stepwise translocation of polypeptide chains across the membrane.

DIP1374
Conserved hypothetical protein; Similar to Corynebacterium glutamicum hypothetical 13.5 kDa protein SWALL:Q9AE08 (EMBL:AF038651) (121 aa) fasta scores: E(): 7.2e-10, 34.83% id in 89 aa, and to Mycobacterium tuberculosis hypothetical 13.0 kDa protein Rv2588c precursor or MT2665 or MTCY227.13 SWALL:YP88_MYCTU (SWALL:Q50633) (115 aa) fasta scores: E(): 5.9e-05, 37.77% id in 90 aa.

DIP2273
Putative integral membrane protein; Similar to Mycobacterium paratuberculosis hypothetical 39.2 kDa protein SWALL:Q9L7M1 (EMBL:AF222789) (353 aa) fasta scores: E(): 1.2e-16, 32.69% id in 312 aa, and to Streptomyces coelicolor integral membrane protein SCH24.05 SWALL:O54569 (EMBL:Y16311) (431 aa) fasta scores: E(): 0.00015, 23.88% id in 448 aa. Note the overlap with downstream gene.

DIP2379
Similar to Mycobacterium tuberculosis putative membrane protein MTV028.12c Rv3921c or MTV028.12c TR:O53599 (EMBL:AL021426) (366 aa) fasta scores: E(): 5.3e-40, 44.72% id in 313 aa, and to Streptomyces coelicolor inner membrane protein SCH24.05 TR:O54569 (EMBL:Y16311) (431 aa) fasta scores: E(): 2.6e-16, 29.74% id in 279 aa. Questionable translational start as N-terminal region is truncated relative to homologues and the start codon is distant from the likely ribosome binding site. Also C-terminus is truncated relative to homologues and ends with KKKKK.

rplB
50S ribosomal protein L2; One of the primary rRNA binding proteins. Required for association of the 30S and 50S subunits to form the 70S ribosome, for tRNA binding and peptide bond formation. It has been suggested to have peptidyltransferase activity; this is somewhat controversial. Makes several contacts with the 16S rRNA in the 70S ribosome. Belongs to the universal ribosomal protein uL2 family.
