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
Your Input:
cysKCysteine synthase; Catalyzes the conversion of O-acetylserine to cysteine. Also acts as a sensor of cysteine availability in the signal transduction pathway modulating CymR activity. When cysteine is present, the pool of O-acetylserine (OAS) is low, which leads to the formation of a CymR- CysK complex and transcriptional repression of the CymR regulon occurs. In the absence of cysteine, the OAS pool is high and the CymR-CysK complex is mostly dissociated, leading to a faster dissociation of CymR from its DNA targets and the lifting of CymR-dependent repression. (308 aa)
tcyPSodium-cystine symporter; Mediates uptake of L-cystine, the oxidized form of L- cysteine. Although it is more specific for L-cystine, it could also transport a much broader range of amino acids and sulfur compounds including S-methylcysteine; Belongs to the dicarboxylate/amino acid:cation symporter (DAACS) (TC 2.A.23) family. (463 aa)
cysH(phospho)adenosine phosphosulfate reductase; Reduction of activated sulfate into sulfite. (233 aa)
cysPSulfate permease; Involved in the import of sulfate. (354 aa)
satSulfate adenylyltransferase; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type e: enzyme. (382 aa)
cysCAdenylylsulfate kinase; Catalyzes the synthesis of activated sulfate; Belongs to the APS kinase family. (197 aa)
sumTUroporphyrinogen III and precorrin-1 C-methyltransferase; Catalyzes both methylations at C-2 and C-7 of uroporphyrinogen III leading to precorrin-1 and precorrin-2; their oxidative esterification gives respectively factor I octamethyl ester and sirohydrochlorin. (257 aa)
sirBSirohydrochlorin ferrochelatase; Chelates iron to the siroheme precursor; Belongs to the CbiX family. SirB subfamily. (261 aa)
sirCPrecorrin-2 dehydrogenase; Catalyzes the dehydrogenation of precorrin-2 to form sirohydrochlorin which is used as a precursor in both siroheme biosynthesis and in the anaerobic branch of adenosylcobalamin biosynthesis; Belongs to the precorrin-2 dehydrogenase / sirohydrochlorin ferrochelatase family. (162 aa)
cysISulfite reductase (hemoprotein beta-subunit); Component of the sulfite reductase complex that catalyzes the 6-electron reduction of sulfite to sulfide. This is one of several activities required for the biosynthesis of L-cysteine from sulfate (Probable); Belongs to the nitrite and sulfite reductase 4Fe-4S domain family. (571 aa)
cysJSulfite reductase (flavoprotein alpha-subunit); Component of the sulfite reductase complex that catalyzes the 6-electron reduction of sulfite to sulfide. This is one of several activities required for the biosynthesis of L-cysteine from sulfate. The flavoprotein component catalyzes the electron flow from NADPH -> FAD -> FMN to the hemoprotein component (Probable). (605 aa)
yxeQPutative catabolic enzyme; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; Product type pe: putative enzyme; Belongs to the PrpD family. (445 aa)
yxePPutative amidohydrolase; Probably catalyzes the deacetylation of N-acetylcysteine (NAC) to acetate and cysteine. Is involved in a S-(2-succino)cysteine (2SC) degradation pathway that allows B.subtilis to grow on 2SC as a sole sulfur source, via its metabolization to cysteine. Belongs to the peptidase M20 family. (380 aa)
yxeOPutative ABC transporter (ATP-binding protein); Probably part of the ABC transporter complex YxeMNO that could be involved in amino-acid import. May transport S-methylcysteine. Responsible for energy coupling to the transport system (Probable). (249 aa)
yxeNPutative ABC transporter (permease); Probably part of the ABC transporter complex YxeMNO that could be involved in amino-acid import. May transport S-methylcysteine. Probably responsible for the translocation of the substrate across the membrane (Probable); Belongs to the binding-protein-dependent transport system permease family. (224 aa)
yxeMPutative ABC transporter (binding lipoprotein); Probably part of the ABC transporter complex YxeMNO that could be involved in amino-acid import. May transport S-methylcysteine; Belongs to the bacterial solute-binding protein 3 family. (264 aa)
yxeLPutative acetyltransferase; Catalyzes the N-acetylation of S-(2-succino)cysteine. Is involved in a S-(2-succino)cysteine (2SC) degradation pathway that allows B.subtilis to grow on 2SC as a sole sulfur source, via its metabolization to cysteine. Moreover, 2SC is a toxic compound in B.subtilis at high exogenous concentrations, and this enzyme relieves 2SC toxicity via N-acetylation; Belongs to the acetyltransferase family. (165 aa)
yxeKPutative monooxygenase; Probably catalyzes the oxygenation of the 2-position of the succinyl moiety of N-acetyl-S-(2-succino)cysteine, causing a spontaneous elimination reaction of the resulting hemithioketal that generates oxaloacetate and N-acetylcysteine (NAC). Is involved in a S- (2-succino)cysteine (2SC) degradation pathway that allows B.subtilis to grow on 2SC as a sole sulfur source, via its metabolization to cysteine; Belongs to the NtaA/SnaA/SoxA(DszA) monooxygenase family. (441 aa)
