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

hypBProbable hydrogenase accessory protein HypB. Homology to hypB of E. coli of 56% (sprot|HYPB_ECOLI). IS REQUIRED FOR THE FORMATION OF HYDROGENASE ISOENZYMES. AFFECTS SOME ASPECT OF THE PROCESSING OF HYDROGENASES and NICKEL INCORPORATION scince HYPB GENE LESIONS CAN BE COMPLEMENTED BY HIGH NICKEL ION CONCENTRATION IN THE MEDIUM. Pfam: HypB/UreG nucleotide-binding domain Tigrfam: hypB: hydrogenase accessory protein Hyp no signal peptide no TMHs; High confidence in function and specificity. (307 aa)    
Predicted Functional Partners:
hypC
Probable hydrogenase assembly chaperon HypC. Homology to hypC of R. leguminosarum of 61% (sprot|HYPC_RHILV). Forms a family of small proteins that are hydrogenase precursor-specific chaperones required for this maturation process. They are believed to keep the hydrogenase precursor in a conformation accessible for metal incorporation. Pfam: HypF/HypC family Tigrfam: hypC_hupF: hydrogenase assembly chaperone no signal peptide no TMHs; Function unclear.

hypD
Hydrogenase expression/formation protein hypD. Homology to hypD of A. eutrophus of 71% (sprot|HYPD_ALCEU). HypD is involved in hydrogenase formation. InterPro: Hydrogenase formation hypA (IPR002780) Pfam: Hydrogenase formation hypA family Tigrfam: hypD: hydrogenase expression/formation no signal peptide no TMHs; High confidence in function and specificity; Belongs to the HypD family.

hypA
Probable hydrogenase nickel inorporation protein hypA; Involved in the maturation of [NiFe] hydrogenases. Required for nickel insertion into the metal center of the hydrogenase.
 
 
 0.978
ureF
Probable urease accessory protein UreF; Required for maturation of urease via the functional incorporation of the urease nickel metallocenter.
  
 
 0.975
hypF
Probable hydrogenase maturation protein HypF; Involved in the maturation of [NiFe] hydrogenases. Along with HypE, it catalyzes the synthesis of the CN ligands of the active site iron of [NiFe]-hydrogenases. HypF functions as a carbamoyl transferase using carbamoylphosphate as a substrate and transferring the carboxamido moiety in an ATP-dependent reaction to the thiolate of the C-terminal cysteine of HypE yielding a protein-S-carboxamide.

azo2062
Conserved hypothetical peptidyl-prolyl cis-trans isomerase. Homology to slyD of E. coli of 41% (sprot|SLYD_ECOLI) but around 30 aa at the C-terminus are missing. Peptidylprolyl isomerases accelerate protein folding by catalyzing the cis-trans isomerization of proline imidic peptide bonds in oligopeptides. InterPro: FKBP-type peptidyl-prolyl cis-trans isomerase (PPIase) (IPR001179). Pfam: FKBP-type peptidyl-prolyl cis-trans isomerase. no signal peptide. no TMHs; Family membership.

hupF
Putative Hydrogenase expression/formation protein hupF,43% similarity to TrEMBL; Q6PTB2. No Signal Peptide or TMH reported present. Has PF01455:HupF/HypC family(IPR001109);The large subunit of [NiFe]-hydrogenase,as well as other nickel metalloenzymes, is synthesized as a precursor devoid of the metalloenzyme active site. This precursor then undergoes a complex post-translational maturation process that requires a number of accessory proteins. The hydrogenase expression/formation proteins (HUPF/HYPC) form a family of small proteins that are hydrogenase precursor-specific chaperones requ [...]
