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

fadD22P-hydroxybenzoyl-AMP ligase FadD22; Catalyzes the adenylation of p-hydroxybenzoic acid (pHBA) to form p-hydroxybenzoic acid-AMP (pHBA-AMP), which is converted directly to p-hydroxybenzoyl-S-FadD22 (pHBA-S-FAdD22) thioester intermediate in a CoA-independent manner by attack of the phosphopantetheine thiol of FadD22. Usually, this intermediate primes the biosynthesis of the phenolphthiocerol (PPOL) by presenting the pHBA starter unit for elongation by Pks15/1, but M.tuberculosis lacks Pks15/1 due to a natural frameshift and thus is unable to produce PPOL. Belongs to the ATP-dependent AMP [...] (705 aa)    
Predicted Functional Partners:
Rv2949c
Chorismate pyruvate lyase; Removes the pyruvyl group from chorismate to provide 4- hydroxybenzoate (4HB). Involved in the synthesis of glycosylated p- hydroxybenzoic acid methyl esters (p-HBADs) and phenolic glycolipids (PGL) that play important roles in the pathogenesis of mycobacterial infections.

fadD29
Fatty-acid-AMP ligase FadD29 (fatty-acid-AMP synthetase) (fatty-acid-AMP synthase); Catalyzes the activation of the long-chain fatty acids (C22- 24 fatty acids) as acyl-adenylates (acyl-AMP), which are then transferred to the multifunctional polyketide synthase PpsA for further chain extension. Involved in the biosynthesis of phenolphthiocerol, which is an important intermediate in the biosynthesis of phenolic glycolipid (mycosid B).
