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

speESpermidine synthase; Catalyzes the irreversible transfer of a propylamine group from the amino donor S-adenosylmethioninamine (decarboxy-AdoMet) to putrescine (1,4-diaminobutane) to yield spermidine. (287 aa)    
Predicted Functional Partners:
speD
S-adenosylmethionine decarboxylase proenzyme; Catalyzes the decarboxylation of S-adenosylmethionine to S- adenosylmethioninamine (dcAdoMet), the propylamine donor required for the synthesis of the polyamines spermine and spermidine from the diamine putrescine; Belongs to the prokaryotic AdoMetDC family. Type 2 subfamily.

speC
Similar to Escherichia coli ornithine decarboxylase, constitutive SpeC or b2965 SWALL:DCOR_ECOLI (SWALL:P21169) (711 aa) fasta scores: E(): 0, 71.78% id in 716 aa, and to Yersinia pestis ornithine decarboxylase SpeC or ypo0960 or y3347 SWALL:Q8ZHE0 (EMBL:AJ414145) (720 aa) fasta scores: E(): 0, 73.61% id in 720 aa.

ECA4274
Similar to Yersinia pestis putative carbon-nitrogen hydrolase ypo0938 or y3324 SWALL:Q8ZHG1 (EMBL:AJ414145) (294 aa) fasta scores: E(): 2.8e-116, 93.87% id in 294 aa, and to Pseudomonas aeruginosa probable hydratase pa0293 SWALL:Q9I6J8 (EMBL:AE004467) (292 aa) fasta scores: E(): 4.5e-79, 65.05% id in 289 aa.

patA
Probable aminotransferase; Catalyzes the aminotransferase reaction from putrescine to 2- oxoglutarate, leading to glutamate and 4-aminobutanal, which spontaneously cyclizes to form 1-pyrroline. This is the first step in one of two pathways for putrescine degradation, where putrescine is converted into 4-aminobutanoate (gamma-aminobutyrate or GABA) via 4- aminobutanal. Also functions as a cadaverine transaminase in a a L- lysine degradation pathway to succinate that proceeds via cadaverine, glutarate and L-2-hydroxyglutarate.

mtn
5'-methylthioadenosine/S-adenosylhomocysteine nucleosidase; Catalyzes the irreversible cleavage of the glycosidic bond in both 5'-methylthioadenosine (MTA) and S-adenosylhomocysteine (SAH/AdoHcy) to adenine and the corresponding thioribose, 5'- methylthioribose and S-ribosylhomocysteine, respectively. Also cleaves 5'-deoxyadenosine, a toxic by-product of radical S-adenosylmethionine (SAM) enzymes, into 5-deoxyribose and adenine. Thus, is required for in vivo function of the radical SAM enzymes biotin synthase and lipoic acid synthase, that are inhibited by 5'-deoxyadenosine accumulatio [...]

speA
Biosynthetic arginine decarboxylase; Catalyzes the biosynthesis of agmatine from arginine.

fliM
Flagellar motor switch protein; FliM is one of three proteins (FliG, FliN, FliM) that forms the rotor-mounted switch complex (C ring), located at the base of the basal body. This complex interacts with the CheY and CheZ chemotaxis proteins, in addition to contacting components of the motor that determine the direction of flagellar rotation.

arnA
Probable formyl transferase; Bifunctional enzyme that catalyzes the oxidative decarboxylation of UDP-glucuronic acid (UDP-GlcUA) to UDP-4-keto- arabinose (UDP-Ara4O) and the addition of a formyl group to UDP-4- amino-4-deoxy-L-arabinose (UDP-L-Ara4N) to form UDP-L-4-formamido- arabinose (UDP-L-Ara4FN). The modified arabinose is attached to lipid A and is required for resistance to polymyxin and cationic antimicrobial peptides; In the C-terminal section; belongs to the NAD(P)-dependent epimerase/dehydratase family. UDP-glucuronic acid decarboxylase subfamily.
   
 
 0.677
masA
Enolase-phosphatase; Bifunctional enzyme that catalyzes the enolization of 2,3- diketo-5-methylthiopentyl-1-phosphate (DK-MTP-1-P) into the intermediate 2-hydroxy-3-keto-5-methylthiopentenyl-1-phosphate (HK- MTPenyl-1-P), which is then dephosphorylated to form the acireductone 1,2-dihydroxy-3-keto-5-methylthiopentene (DHK-MTPene). Belongs to the HAD-like hydrolase superfamily. MasA/MtnC family.
