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.

dgkDeoxyguanosine kinase; Plays an essential role in generating the deoxyribonucleotide precursors dGTP for DNA metabolism. Highly specific toward deoxyguanosine (dGuo) and deoxyinosine (dIno). Only marginal activity is observed with guanosine. UTP is slightly more efficient as phosphate donor than CTP, ATP and GTP. (207 aa)    
Predicted Functional Partners:
dck
Deoxyadenosine/deoxycytidine kinase; Plays an essential role in generating the deoxyribonucleotide precursors dATP AND dCTP for DNA metabolism. The phosphate acceptor specificity is strict toward deoxyadenosine (dAdo) and deoxycytidine (dCyd). The specificity toward the sugar moiety of the nucleoside is less strict. Both 2-deoxyribose, ribose, and arabinose nucleosides are phosphorylated, although the 2-deoxyribonucleosides are preferred. The phosphate donor specificity is dependent on the deoxyribonucleoside substrate, but GTP is efficient with both deoxycytidine and deoxyadenosine. O [...]

pupG
Purine nucleoside phosphorylase; The purine nucleoside phosphorylases catalyze the phosphorolytic breakdown of the N-glycosidic bond in the beta- (deoxy)ribonucleoside molecules, with the formation of the corresponding free purine bases and pentose-1-phosphate. Cleaves guanosine, inosine, 2'-deoxyguanosine and 2'-deoxyinosine.

gmk
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP.

ctaC
Cytochrome caa3 oxidase (subunit II); Subunits I and II form the functional core of the enzyme complex. Electrons originating in cytochrome c are transferred via heme a and Cu(A) to the binuclear center formed by heme a3 and Cu(B).

folK
7,8-dihydro-6-hydroxymethylpterin pyrophosphokinase; Evidence 2a: Function of homologous gene experimentally demonstrated in an other organism; Product type e: enzyme; Belongs to the HPPK family.

deoD
Purine nucleoside phosphorylase; Cleavage of adenosine and its derivatives; Belongs to the PNP/UDP phosphorylase family.

yfkN
Exported 2',3'-cyclic-nucleotide 2'-phosphodiesterase, 2' (or 3') nucleotidase and 5' nucleotidase; Catalyzes the release of inorganic phosphate from 2',3'- cyclic nucleotides through consecutive 2',3'-phosphodiesterase and 3'- (or 2') nucleotidase activities. Also possesses a 5'-nucleotidase activity. Does not catalyze the release of inorganic phosphate from 3',5'-cyclic nucleotides. Probably plays a role in the cellular reprocessing of nucleotides present in the medium, under conditions of phosphate shortage.

yesF
Putative oxidoreductase; 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 NmrA-type oxidoreductase family.

yhfK
Putative epimerase; Evidence 3: Function proposed based on presence of conserved amino acid motif, structural feature or limited homology; putative enzyme.

yaaH
Spore peptidoglycan hydrolase; N-acetylglucosaminidase involved in cortex peptidoglycan degradation during germination. Cleaves only partially degraded spore peptidoglycans. Recognizes muramic acid delta-lactam residues specific to spore peptidoglycans.
