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

ligJ4-oxalomesaconate hydratase; Contributes to the degradation of lignin at the level of the protocatechuate 4,5-cleavage pathway. Catalyzes the hydration of the double bond of (3Z)-2-keto-4-carboxy-3-hexenedioate (KCH) to (4S)-4- carboxy-4-hydroxy-2-oxoadipate (CHA, also named (2S)-2-hydroxy-4- oxobutane-1,2,4-tricarboxylate). Is involved in the catabolism of both vanillate and syringate. (341 aa)    
Predicted Functional Partners:
ligK
4-hydroxy-4-methyl-2-oxoadipate aldolase; Contributes to the degradation of lignin, being involved in the final step of the protocatechuate 4,5-cleavage pathway. Catalyzes the conversion of 4-carboxy-4-hydroxy-2-oxoadipate (CHA, also named 2- hydroxy-4-oxobutane-1,2,4-tricarboxylate) to pyruvate and oxaloacetate but also the decarboxylation of oxaloacetate to pyruvate and CO2. Is essential for catabolism and utilization of vanillate and syringate. Is also able to catalyze the formation of 4-hydroxy- 4-methyl-2-oxoglutarate (HMG) from two molecules of pyruvate ; Belongs to the LigK/PcmE [...]

ligB
Protocatechuate 4,5-dioxygenase beta chain; Responsible for the aromatic ring fission of protocatechuate.
 
   
 0.935
SLG_19060
Putative aldolase.
 
  
 0.932
ligI
2-pyrone-4,6-dicarboxylic acid hydrolase; Contributes to the degradation of lignin at the level of the protocatechuate 4,5-cleavage pathway. Catalyzes the hydrolysis of 2-pyrone-4,6-dicarboxylate (PDC) to (4E)-oxalomesaconate (OMA). The keto form of OMA can tautomerize into the enol form, 4-carboxy-2-hydroxymuconate (CHM), under certain pH conditions. Also catalyzes the reverse reaction. Is essential for the growth of Sphingobium sp. SYK-6 on vanillate but is not responsible for the growth of this strain on syringate. Belongs to the metallo-dependent hydrolases superfamily. PDC hydrola [...]

ligC
4-carboxy-2-hydroxymuconate-6-semialdehyde dehydrogenase; Involved in the degradation of protocatechuate (PCA) via the PCA 4,5-cleavage pathway. Catalyzes the oxidation of the hemiacetal form of 4-carboxy-2-hydroxymuconate-6-semialdehyde (CHMS) to produce 2- pyrone-4,6-dicarboxylate (PDC). LigC has 10-times-higher affinity to NADP than to NAD.
