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

nanHSialidase; Cleaves the terminal sialic acid (N-acetyl neuraminic acid) from carbohydrate chains in glycoproteins providing free sialic acid which can be used as carbon and energy sources. Sialidases have been suggested to be pathogenic factors in microbial infections. (412 aa)
cysBTranscriptional regulator for cysteine regulon; This protein is a positive regulator of gene expression for the cysteine regulon, a system of 10 or more loci involved in the biosynthesis of L-cysteine from inorganic sulfate. The inducer for CysB is N-acetylserine. CysB inhibits its own transcription. (324 aa)
hmpADihydropteridine reductase 2; Is involved in NO detoxification in an aerobic process, termed nitric oxide dioxygenase (NOD) reaction that utilizes O(2) and NAD(P)H to convert NO to nitrate, which protects the bacterium from various noxious nitrogen compounds. Therefore, plays a central role in the inducible response to nitrosative stress. Belongs to the globin family. Two-domain flavohemoproteins subfamily. (396 aa)
gcvARegulator of gcv operon; LysR family; similar to E. coli positive regulator of gcv operon (AAC75850.1); Blastp hit to AAC75850.1 (305 aa), 98% identity in aa 1 - 305; Belongs to the LysR transcriptional regulatory family. (305 aa)
gcvPGlycine cleavage complex protein P; The glycine cleavage system catalyzes the degradation of glycine. The P protein binds the alpha-amino group of glycine through its pyridoxal phosphate cofactor; CO(2) is released and the remaining methylamine moiety is then transferred to the lipoamide cofactor of the H protein; Belongs to the GcvP family. (957 aa)
gcvHGlycine cleavage complex protein H; The glycine cleavage system catalyzes the degradation of glycine. The H protein shuttles the methylamine group of glycine from the P protein to the T protein. (129 aa)
gcvTGlycine cleavage complex protein T; The glycine cleavage system catalyzes the degradation of glycine. (364 aa)
metCCystathionine beta-lyase; Catalyzes the cleavage of cystathionine to homocysteine, pyruvate and ammonia during methionine biosynthesis. (395 aa)
cysESerine acetyltransferase. (SW:CYSE_SALTY); Belongs to the transferase hexapeptide repeat family. (273 aa)
ilvYPositive LysR family regulator for ilvC; This protein activates the transcription of the IlvC gene in the presence of acetolactate or acetohydroxybutyrate. IlvY is also a negative regulator of its own expression; Belongs to the LysR transcriptional regulatory family. (295 aa)
metRRegulator for metE and metH; Control of the last step in methionine biosynthesis; MetR is a positive activator of the metA, metE and metH genes. It is also a negative regulator of its own expression; Belongs to the LysR transcriptional regulatory family. (317 aa)
metE5-methyltetrahydropteroyltriglutamate- homocysteine S-methyltransferase; Catalyzes the transfer of a methyl group from 5- methyltetrahydrofolate to homocysteine resulting in methionine formation; Belongs to the vitamin-B12 independent methionine synthase family. (754 aa)
metJTranscriptional repressor of all met genes but metF; This regulatory protein, when combined with SAM (S- adenosylmethionine) represses the expression of the methionine regulon and of enzymes involved in SAM synthesis. It is also autoregulated (By similarity); Belongs to the MetJ family. (105 aa)
metBSimilar to E. coli cystathionine gamma-synthase (AAC76921.1); Blastp hit to AAC76921.1 (386 aa), 96% identity in aa 1 - 386. (386 aa)
