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

birABirA protein; Rv3279c, (MTCY71.19c), len: 266 aa. Possible birA,bifunctional protein: biotin operon repressor and biotin--[acetyl-CoA-carboxylase] synthetase, equivalent to Q9CCL3|BIRA|ML0732 biotin APO-protein ligase from Mycobacterium leprae (274 aa), FASTA scores: opt: 1189,E(): 2.3e-66, (71.2% identity in 271 aa overlap). But as it lacks a BirA h-t-h domain at N-terminus, may simply be biotin apo-protein ligase. Also similar to others e.g. Q9CNX6|BIRA|PM0296 from Pasteurella multocida (312 aa),FASTA scores: opt: 347, E(): 2.7e-14, (32.95% identity in 270 aa overlap); Q9HWC0|BIRA|PA [...] (266 aa)    
Predicted Functional Partners:
