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

pdaAExported N-acetylmuramic acid deacetylase; Catalyzes the deacetylation of N-acetylmuramic acid (MurNAc) residues in glycan strands of peptidoglycan, leading to the formation of muramic delta-lactam residues in spore cortex, after transpeptidation of deacetylated muramic acid residues. PdaA probably carries out both deacetylation and lactam ring formation and requires the product of CwlD activity on peptidoglycan as a substrate. Is required for germination. Cannot use chitin oligomer (hexa-N- acetylchitohexaose) as a substrate; Belongs to the polysaccharide deacetylase family. (263 aa)    
Predicted Functional Partners:
ydaM
Putative glycosyltransferase associated to biofilm formation; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
 
  
 0.945
cwlD
N-acetylmuramoyl-L-alanine amidase; Cleaves the peptide side chain from the N-acetylmuramic acid residues in peptidoglycan. This is a step in the formation of muramic delta-lactam residues in spore cortex.
  
  
 0.934
yvbX
Putative epimerase modification of peptidoglycan; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme; Belongs to the glycosyl hydrolase 18 family.
 
      0.882
ydhD
Spore cortex lytic enzyme; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type cp: cell process; Belongs to the glycosyl hydrolase 18 family. Chitinase class II subfamily.
 
 
  
 0.743
spoIVA
Morphogenetic stage IV sporulation protein; ATPase. Has a role at an early stage in the morphogenesis of the spore coat outer layers. Its ATP hydrolysis is required for proper assembly of the spore coat. Forms a basement layer around the outside surface of the forespore and self-assembles irreversibly into higher order structures by binding and hydrolyzing ATP thus creating a durable and stable platform upon which thereafter morphogenesis of the coat can take place. Required for proper localization of spore coat protein CotE and sporulation-specific proteins including SpoVM.
  
  
 0.685
yfjT
Conserved hypothetical protein; Evidence 4: Homologs of previously reported genes of unknown function.
  
    0.587
spoIIAB
Anti-sigma factor (antagonist of sigma(F)) and serine kinase; Binds to sigma F and blocks its ability to form an RNA polymerase holoenzyme (E-sigma F). Phosphorylates SpoIIAA on a serine residue. This phosphorylation may enable SpoIIAA to act as an anti- anti-sigma factor that counteracts SpoIIAB and thus releases sigma F from inhibition.
  
  
 0.508
sspA
Small acid-soluble spore protein (alpha-type SASP); SASP are bound to spore DNA. They are double-stranded DNA- binding proteins that cause DNA to change to an a-like conformation. They protect the DNA backbone from chemical and enzymatic cleavage and are thus involved in dormant spore's high resistance to UV light.
   
  
 0.506
ybaK
Putative alkylated deoxynucleotide triphosphohydrolase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme.
   
  
 0.501
spoVD
Penicillin-binding protein; Penicillin-binding protein with an unknown catalytic activity. May have a specialized role in the morphogenesis of spore cortex, which is a modified form of peptidoglycan. Pore cortex formation is determined primarily by the mother cell.
