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

SecA2COG0653 Preprotein translocase subunit SecA (ATPase, RNA helicase). (793 aa)    
Predicted Functional Partners:
secA
Preprotein translocase subunit SecA; 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; Belongs to the SecA family.
  
  
 
0.907
secY-2
Preprotein translocase subunit SecY; Part of the accessory SecA2/SecY2 system specifically required for export of possible cell wall proteins. The central subunit of a protein translocation channel.
 
 
 
 0.898
gtfB
Hypothetical protein; Required for polymorphic O-glycosylation of the serine-rich repeat protein in this bacteria. A stabilizing protein that is part of the accessory SecA2/SecY2 system specifically required to export serine-rich repeat cell wall proteins usually encoded upstream in the same operon. The GtfA-GtfB complex adds GlcNAc from UDP-GlcNAc to the substrate protein, attaching the first sugar residue. Stabilizes the glycosylation activity of GtfA. Has no N-acetylglucosaminyl transferase activity on its own.
 
 
 
 0.833
secG
Preprotein translocase subunit SecG; Involved in protein export. Participates in an early event of protein translocation; Belongs to the SecG family.
   
 
 0.812
gtfA
Glycosyltransferase, putative teichoic acid biosynthesis protein; Required for polymorphic O-glycosylation of the serine-rich repeat protein in this bacteria. Catalyzes the first step in glycosylation by transferring N-acetylglucosamine from UDP-GlcNAc to serine residues in the substrate protein. Part of the accessory SecA2/SecY2 system specifically required to export serine-rich repeat cell wall proteins usually encoded upstream in the same operon.
   
 
 0.801
secE
COG0690 Preprotein translocase subunit SecE; Belongs to the SecE/SEC61-gamma family.
    
 
 0.736
polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity.
 
  
 0.731
secY
Preprotein translocase subunit SecY; 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.
 
 
 
 0.721
recA
Recombinase A; Can catalyze the hydrolysis of ATP in the presence of single- stranded DNA, the ATP-dependent uptake of single-stranded DNA by duplex DNA, and the ATP-dependent hybridization of homologous single-stranded DNAs. It interacts with LexA causing its activation and leading to its autocatalytic cleavage; Belongs to the RecA family.
 
   
 0.694
Asp3
Hypothetical protein.
 
   
 0.690
