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

CAZ96977.1Conserved hypothetical lipoprotein; Contains a prokaryotic lipoprotein signal peptide cleaved between the residues 24 and 25; Localized in the outer membrane; Conserved hypothetical protein. (233 aa)    
Predicted Functional Partners:
ppk2
Polyphosphate kinase 2; Ppk2 was first identified in Pseudomonas aeruginosa by Zhang and cowokers (PNAS, 2006). Ppk2 belongs to a polyphosphate kinase family unrelated to that of Ppk1. Pkk2 also distinguished from PPK1 by the following: synthesis of poly P from GTP or ATP, a preference for Mn2+ over Mg2+, and a stimulation by poly P. The reverse reaction, a poly P-driven nucleoside diphosphate kinase synthesis of GTP from GDP, is 75-fold greater than the forward reaction, poly P synthesis from GTP. Localized in the cytoplasm; High confidence in function and specificity.

CAZ96979.1
Family M28 contains aminopeptidases and carboxypeptidases with two co-catalytic zinc ions (I and II). Each zinc ion is tetrahedrally co-ordinated, with three amino acid ligands plus activated water; one aspartate residue binds both metal ions. The zinc ligands occur in the sequence in the order His (II), Asp (I and II), Glu (I), Asp or Glu (II) and His (I). In addition, two other residues, an Asp and a Glu, are believed to be important for catalysis. Four of these residues occur in the motifs His-Xaa-Asp and Glu-Glu. Features a signal peptide cleaved between the residues 20 and 21. Loc [...]
