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

AhcyAdenosylhomocysteinase (Ahcy) encodes S-adenosyl-L-homocysteine hydrolase, the rate-limiting enzyme in methionine metabolism. This tetrameric enzyme catalyzes the reversible hydrolysis of S-Adenosylhomocysteine (SAH) to adenosine and L-homocysteine. The function of Ahcy product is required to maintain proper concentrations of SAH, which serves as an inhibitor of S-adenosylmethionine-dependent methylation reactions. (432 aa)    
Predicted Functional Partners:
Cbs
Cystathionine beta-synthase (Cbs) encodes an enzyme involved in endoplasmic reticulum stress response; Belongs to the cysteine synthase/cystathionine beta- synthase family.

CG10623
CG10623 protein; Zinc ion binding; betaine-homocysteine S-methyltransferase activity; S-adenosylmethionine-homocysteine S-methyltransferase activity. It is involved in the biological process described with: S-methylmethionine cycle; methionine biosynthetic process.

Eip55E
Ecdysone-induced protein 55E (Eip55E) encodes a protein involved in glutathione biosynthesis.

AhcyL1
Adenosylhomocysteinase like 1 (AhcyL1) encodes a protein that, together with the product of AhcyL2, belongs to AHCY-like proteins. AhcyL1 and AhcyL2 products have lost their canonical enzymatic functions due to critical mutations in their AHCY-domains. However, via hetero-multimerization, the products of AhcyL1 and AhcyL2 can suppress the activity of the enzyme encoded by Ahcy, which catalyzes the hydrolysis of S-Adenosylhomocysteine. The presence of a N-terminal IRBIT domain confers AhcyL1 and AhcyL2 proteins new functions in Ca[2+] signaling, intracellular pH regulation and productio [...]

Kyat
Kynurenine aminotransferase, isoform A; Pyridoxal phosphate binding; cysteine-S-conjugate beta-lyase activity; kynurenine-oxoglutarate transaminase activity. It is involved in the biological process described with: biosynthetic process; kynurenine metabolic process.
