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

kshA
Oxygenase component of 3-ketosteroid-9-alpha-hydroxylase KshA; Involved in the degradation of cholesterol. Catalyzes the introduction of a 9a-hydroxyl moiety into 1,4-androstadiene-3,17-dione (ADD) to yield the 9alpha-hydroxy-1,4-androstadiene-3,17-dione (9OHADD) intermediate which spontaneously form 3-hydroxy-9,10-seconandrost- 1,3,5(10)-triene-9,17-dione (HSA) via the meta-cleavage of ring B with concomitant aromatization of ring A. KSH is also able to use 4- androstene-3,17-dione (AD), 3-oxo-23,24-bisnorcholesta-4-en-22-oate (4- BNC), 3-oxo-23,24-bisnorcholesta-1,4-dien-22-oate (1,4 [...]

fadE34
Probable acyl-CoA dehydrogenase FadE34; Involved in the second cycle of side chain dehydrogenation in the beta-oxidation of cholesterol catabolism. It contributes partly to the virulence by increasing the efficiency of beta-oxidation. Catalyzes the highly specific dehydrogenation of acyl-CoA ester side chains of 3- oxo-chol-4-en-24-oyl-CoA (3-OCO-CoA) to yield 3-oxochol-4,22-dien-24- oyl-CoA.

hsaC
3,4-DHSA dioxygenase; Catalyzes the meta-cleavage of 3,4-dihydroxy-9,10- seconandrost-1,3,5(10)-triene-9,17-dione (3,4-DHSA) to produce 4,5- 9,10-diseco-3-hydroxy-5,9,17-trioxoandrosta-1(10),2-diene-4-oic acid (4,9-DSHA).
  
  
 0.847
hsaA
Flavin-dependent monooxygenase, oxygenase subunit HsaA; Catalyzes the o-hydroxylation of 3-hydroxy-9,10-secoandrosta- 1,3,5(10)-triene-9,17-dione (3-HSA) to 3,4-dihydroxy-9,10-secoandrosta- 1,3,5(10)-triene-9,17-dione (3,4-DHSA) in the catabolism of cholesterol. Can use either FADH(2) or FMNH(2) as flavin cosubstrate. Also catalyzes the o-hydroxylation of a range of p-substituted phenols to generate the corresponding catechols.

fadD19
Fatty-acid-CoA ligase FadD19 (fatty-acid-CoA synthetase) (fatty-acid-CoA synthase); Catalyzes the activation of long-chain fatty acids as acyl- coenzyme A (acyl-CoA), which are then transferred to the multifunctional polyketide synthase (PKS) type III for further chain extension.
