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

spr1575Hypothetical protein. (149 aa)    
Predicted Functional Partners:
spr1576
Conserved hypothetical protein.
 
  
 0.969
pkn2
Eukaryotic-type serine/threonine kinase; Protein kinase involved in signal transduction pathways that regulate various cellular processes. Likely senses intracellular peptidoglycan subunits present in the cell division septa of actively growing cells; thus, intracellular unlinked peptidoglycan may serve as the signal molecules that trigger StkP phosphorylation activity on a set of substrates. Plays a crucial role in the regulation of cell shape and cell division of S.pneumoniae through control of at least DivIVA activity. Identified target substrates that are specifically phosphorylate [...]
       0.649
sunL
rRNA methylase; Specifically methylates the cytosine at position 967 (m5C967) of 16S rRNA.
  
    0.601
spr1574
Degenerate transposase (orf1).
       0.586
pppL
Phosphoprotein phosphatase; Protein phosphatase able to dephosphorylate StkP-P and other phosphorylated protein substrates. PhpP and its cognate protein kinase StkP appear to constitute a functional signaling couple in vivo, PhpP's primary role being probably to control phosphorylation levels of StkP and of its targets. PhpP thus performs an essential control of StkP activity (By similarity); Belongs to the PP2C family.
       0.547
fmt
Methionyl-tRNA formyltransferase; Attaches a formyl group to the free amino group of methionyl- tRNA(fMet). The formyl group appears to play a dual role in the initiator identity of N-formylmethionyl-tRNA by promoting its recognition by IF2 and preventing the misappropriation of this tRNA by the elongation apparatus; Belongs to the Fmt family.
       0.540
priA
Primosomal replication factor Y; Involved in the restart of stalled replication forks. Recognizes and binds the arrested nascent DNA chain at stalled replication forks. It can open the DNA duplex, via its helicase activity, and promote assembly of the primosome and loading of the major replicative helicase DnaB onto DNA; Belongs to the helicase family. PriA subfamily.
       0.530
IS1381-4
Tranposase (orf2).
       0.511
spr1572
Hypothetical protein.
       0.459
rpoZ
Hypothetical protein; Promotes RNA polymerase assembly. Latches the N- and C- terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits.
