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

all5339Phycocyanobilin lyase CpcT; Catalyzes the site-selective attachment of phycocyanobilin (PCB) to 'Cys-154' of C-phycocyanin subunit beta (CpcB) and to 'Cys- 153' of phycoerythrocyanin subunit beta (PecB). Does not have chromophore lyase activity for ApcA1, ApcA2, ApcB, ApcD, ApcF or PecA. Belongs to the CpcT/CpeT biliprotein lyase family. (199 aa)

Phycocyanobilin lyase CpcS 1; Catalyzes the site-selective attachment of phycocyanobilin (PCB) to 'Cys-82' in CpcB and 'Cys-83' in PecB. Also able to add PCB to ApcA1, ApcA2, ApcB, ApcD and ApcF, but not PecA. In vitro can be made to add phycoerythrobilin, a non-physiological substrate, to its target proteins (using genes from Fremyella diplosiphon PCC 7601). Binds PCB extremely rapidly, followed by a much slower phase of PCB transfer to the apo-acceptor protein. This suggests that the lyase has a chaperone- like function, and may serve to regulate the manner (possibly the conformation [...]

Putative phycocyanobilin lyase CpcS 2; Covalently attaches a chromophore to Cys residue(s) of phycobiliproteins (Potential). In vitro does not act as a chromophore lyase for ApcA1, ApcA2, ApcB, ApcD, ApcF, CpcB or PecB, the lyase activity is therefore unsure.

apcB
Allophycocyanin beta subunit; Light-harvesting photosynthetic bile pigment-protein from the phycobiliprotein complex. Allophycocyanin has a maximum absorption at approximately 650 to 653 nanometers.
  
   
 0.824
cpcC
Phycocyanin-associated rod linker protein; Rod linker protein, associated with phycocyanin. Linker polypeptides determine the state of aggregation and the location of the disk-shaped phycobiliprotein units within the phycobilisome and modulate their spectroscopic properties in order to mediate a directed and optimal energy transfer.
