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:
cysK2S-sulfocysteine synthase; Catalyzes the synthesis of S-sulfocysteine, utilizing O- phosphoserine (OPS) and thiosulfate as substrates. To a lesser extent, can also use sulfide as donor substrate, producing L-cysteine. CysK2 thus provides a third metabolic route to cysteine, either directly using sulfide as donor or indirectly via S-sulfocysteine. S- sulfocysteine might also act as a signaling molecule triggering additional responses in redox defense in the pathogen upon exposure to reactive oxygen species during intracellular survival or dormancy. Cannot utilize thiocarboxylated CysO as [...] (372 aa)
cysMO-phosphoserine sulfhydrylase; Catalyzes the formation of a covalent CysO-cysteine adduct via a sulfur transfer, using the thiocarboxylated sulfur carrier protein CysO-COSH as sulfur donor and O-phospho-L-serine (OPS) as sulfur acceptor. Can also use sodium sulfide as sulfur donor in vitro, albeit with less efficiency, but not thiosulfate or thio-nitro- benzoate. O-acetylserine (OAS) is a very poor substrate in comparison with OPS. May be of particular importance for cysteine biosynthesis in the persistent phase of M.tuberculosis; Belongs to the cysteine synthase/cystathionine beta- sy [...] (323 aa)
cysK1O-acetylserine sulfhydrylase; Catalyzes the conversion of O-acetylserine (OAS) to cysteine through the elimination of acetate and addition of hydrogen sulfide. Belongs to the cysteine synthase/cystathionine beta- synthase family. (310 aa)
cysEProbable serine acetyltransferase CysE (sat); Catalyzes the acetylation of serine by acetyl-CoA to produce O-acetylserine (OAS); Belongs to the transferase hexapeptide repeat family. (229 aa)
moeB1Probable adenylyltransferase/sulfurtransferase MoeZ; Catalyzes the conversion of the sulfur carrier protein CysO to CysO-thiocarboxylate. The reaction is thought to proceed in two steps: first, ATP-dependent activation of CysO as acyl-adenylate (CysO- COOAMP), followed by sulfur transfer to give CysO-thiocarboxylate (CysO-COSH) (Probable). The sulfur source is unknown. (392 aa)
