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.

appCOligopeptide transport system permease protein appC. This protein is a component of an oligopeptide permease a binding protein-dependent transport system. This APP system can completely substitute for the OPP system in both sporulation and genetic competence though unlike OPP is incapable of transporting tripeptides. Probably responsible for the translocation of the substrate across the membrane (By similarity). pts-Glc: PTS system maltose and gluco; High confidence in function and specificity. (470 aa)    
Predicted Functional Partners:
appB
Putative Oligopeptide ABC transporter, permease protein; Dipeptide transport system permease protein dppB. Part of the binding-protein-dependent transport system for dipeptides; probably responsible for the translocation of the substrate across the membrane. InterPro: Binding-protein-dependent transport systems inner membrane component crcB: crcB protein; High confidence in function and specificity.
