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

MJ_0936Conserved hypothetical protein; Shows phosphodiesterase activity, hydrolyzing phosphodiesters bonds in the artificial chromogenic substrates bis-p-nitrophenyl phosphate (bis-pNPP), and less efficiently thymidine 5'-monophosphate p-nitrophenyl ester (pNP-TMP) and p-nitrophenylphosphorylcholine (pNPPC). No catalytic activity was found toward cAMP or cGMP, nucleotides or phospholipase substrates such as phosphatidylcholine. The physiological substrate is unknown. (166 aa)

purD
Phosphoribosylamine--glycine ligase (purD); Similar to GB:J02732 SP:P12039 PID:143374 GB:AL009126 percent identity: 33.73; identified by sequence similarity; putative.

MJ_0935
Conserved hypothetical protein; Similar to GB:AE000666 percent identity: 31.97; identified by sequence similarity; putative.

MJ_0736
Alkyl hydroperoxide reductase; Thiol-specific peroxidase that catalyzes the reduction of hydrogen peroxide and organic hydroperoxides to water and alcohols, respectively. Plays a role in cell protection against oxidative stress by detoxifying peroxides.
  
 
 0.793
MJ_0226
Conserved hypothetical protein; Pyrophosphatase that catalyzes the hydrolysis of nucleoside triphosphates to their monophosphate derivatives, with a high preference for the non-canonical purine nucleotides xanthosine triphosphate (XTP), deoxyinosine triphosphate (dITP) and ITP. Probably functions as a house- cleaning enzyme that removes non-canonical purine nucleotides from the nucleotide pool, thus preventing their incorporation into DNA/RNA and avoiding chromosomal lesions. Shows very low activity on GTP or dGTP, both of which are hydrolyzed more than 100-fold less efficiently than X [...]

GTP-binding protein homologue (yphC); Similar to PID:1146219 SP:P50743 GB:AL009126 percent identity: 26.99; identified by sequence similarity; putative.
