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.

lepBLepB protein; Signal peptidase I (EC 3.4.21.89) (SPase I) (Leader peptidase I). SPase I is an integral membrane protein that is anchored in the cytoplasmic membrane by one or two N-terminal transmembrane domains, with the main part of the protein protuding in the periplasmic space. SPase I can cleave N-terminal leader sequences of nonlipoprotein that are exported by the SecYEG pathway or the twin arginine translocation (Tat) pathway. Pfam: Peptidase_S26 probable 2 TMH no signal peptide; High confidence in function and specificity. (262 aa)    
Predicted Functional Partners:
lepA
Probable GTP-binding protein; Required for accurate and efficient protein synthesis under certain stress conditions. May act as a fidelity factor of the translation reaction, by catalyzing a one-codon backward translocation of tRNAs on improperly translocated ribosomes. Back-translocation proceeds from a post-translocation (POST) complex to a pre- translocation (PRE) complex, thus giving elongation factor G a second chance to translocate the tRNAs correctly. Binds to ribosomes in a GTP- dependent manner.

rnc
Putative Ribonuclease III; Digests double-stranded RNA. Involved in the processing of primary rRNA transcript to yield the immediate precursors to the large and small rRNAs (23S and 16S). Processes some mRNAs, and tRNAs when they are encoded in the rRNA operon. Processes pre-crRNA and tracrRNA of type II CRISPR loci if present in the organism.
  
 
 0.912
era
Probable GTP-binding protein; An essential GTPase that binds both GDP and GTP, with rapid nucleotide exchange. Plays a role in 16S rRNA processing and 30S ribosomal subunit biogenesis and possibly also in cell cycle regulation and energy metabolism.
  
    0.828
rimO
Hypothetical protein; Catalyzes the methylthiolation of an aspartic acid residue of ribosomal protein S12; Belongs to the methylthiotransferase family. RimO subfamily.
  
 
  0.805
minE
Putative cell division topological specificity factor; Prevents the cell division inhibition by proteins MinC and MinD at internal division sites while permitting inhibition at polar sites. This ensures cell division at the proper site by restricting the formation of a division septum at the midpoint of the long axis of the cell.
   
    0.805
pdxJ
Pyridoxine biosynthesis; Catalyzes the complicated ring closure reaction between the two acyclic compounds 1-deoxy-D-xylulose-5-phosphate (DXP) and 3-amino- 2-oxopropyl phosphate (1-amino-acetone-3-phosphate or AAP) to form pyridoxine 5'-phosphate (PNP) and inorganic phosphate.
 
   
 0.786
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.

azo1741
Putative DNA-ligase like protein Rv0938/MT0965. dnl1: DNA ligase I ATP-dependent; Specificity unclear; ORF4.

azo1641
Conserved hypothetical secreted protein. Homology with NE2325 of N.europaea of 41% (tremble:Q82SJ5) No domains predicted. Signal peptide Present. No TMH reported; Conserved hypothetical protein.
  
    0.765
lig2
DNA ligase (EC 6.5.1.1) (Polydeoxyribonucleotide synthase [ATP]). This protein seals during DNA replication DNA recombination and DNA repair nicks in double-stranded DNA (By similarity); High confidence in function and specificity.
