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

ugtPUDP-glucose diacylglyceroltransferase; Processive glucosyltransferase involved in the biosynthesis of both the bilayer- and non-bilayer-forming membrane glucolipids. Is able to successively transfer up to three glucosyl residues to diacylglycerol (DAG), thereby catalyzing the formation of beta- monoglucosyl-DAG (3-O-(beta-D-glucopyranosyl)-1,2-diacyl-sn-glycerol), beta-diglucosyl-DAG (3-O-(beta-D-glucopyranosyl-beta-(1->6)-D- glucopyranosyl)-1,2-diacyl-sn-glycerol) and beta-triglucosyl-DAG (3-O- (beta-D-glucopyranosyl-beta-(1->6)-D-glucopyranosyl-beta-(1->6)-D- glucopyranosyl)-1,2-diac [...] (382 aa)    
Predicted Functional Partners:
ftsZ
Cell-division initiation protein; Essential cell division protein that forms a contractile ring structure (Z ring) at the future cell division site. The regulation of the ring assembly controls the timing and the location of cell division. One of the functions of the FtsZ ring is to recruit other cell division proteins to the septum to produce a new cell wall between the dividing cells. Binds GTP and shows GTPase activity.

ltaSA
Exported glycerol phosphate lipoteichoic acid synthetase and anion-binding protein; Catalyzes the polymerization of lipoteichoic acid (LTA) polyglycerol phosphate, a reaction that presumably uses phosphatidylglycerol (PG) as substrate.
  
 
 0.982
ltaSB
Enzyme responsible for polyglycerolphosphate LTA synthesis; Catalyzes the polymerization of lipoteichoic acid (LTA) polyglycerol phosphate, a reaction that presumably uses phosphatidylglycerol (PG) as substrate; Belongs to the LTA synthase family.
  
 
 0.969
dagK
Diacylglycerol kinase; Catalyzes the phosphorylation of diacylglycerol (DAG) into phosphatidic acid. Is a key enzyme involved in the production of lipoteichoic acid by reintroducing DAG formed from the breakdown of membrane phospholipids into the phosphatidylglycerol biosynthetic pathway. Is more active toward long-chain DAG compared with short-chain DAG. Is not able to phosphorylate substrates other than DAG, such as monoacylglycerol, ceramide, undecaprenol, phosphatidylinositol, or sphingosine; Belongs to the diacylglycerol/lipid kinase family.
     
 0.946
gtaB
UTP-glucose-1-phosphate uridylyltransferase; Catalyzes the formation of UDP-glucose from glucose-1- phosphate and UTP. This is an intermediate step in the biosynthesis of diglucosyl-diacylglycerol (Glc2-DAG), i.e. the predominant glycolipid found in B.subtilis membrane, which is also used as a membrane anchor for lipoteichoic acid (LTA). Has a role in the biosynthesis of all phosphate-containing envelope polymers, since UDP-glucose serves as a glucosyl donor not only for the biosynthesis of LTA but also for wall teichoic acids (WTAs). Is required for biofilm formation. This is likely d [...]

estA
Secreted alkaliphilic lipase; Active toward p-nitrophenyl esters and triacylglycerides with a marked preference for esters with C8 acyl groups. Belongs to the AB hydrolase superfamily.
     
  0.900
estB
Secreted esterase / lipase; An esterase which preferentially hydrolyzes triacylglyceride substrates with short chain fatty acids (less than C10) with the maximum activity towards tricaprylin (C8:0). Active against p- nitrophenylesters with fatty acid chain lengths from C6 to C18.
     
  0.900
mprF
Phosphatidylglycerol lysyltransferase involved in lysinylation of phospholipids; Catalyzes the transfer of a lysyl group from L-lysyl- tRNA(Lys) to membrane-bound phosphatidylglycerol (PG), which produces lysylphosphatidylglycerol (LPG), one of the components of the bacterial membrane with a positive net charge. LPG synthesis contributes to the resistance to cationic antimicrobial peptides (CAMPs) and likely protects B.subtilis against its own CAMPs and against those produced by competiting microorganisms (bacteriocins). In fact, the modification of anionic phosphatidylglycerol with po [...]

pgcA
Alpha-phosphoglucomutase; Catalyzes the interconversion between glucose-6-phosphate and alpha-glucose-1-phosphate. This is the first step in the biosynthesis of diglucosyl-diacylglycerol (Glc2-DAG), i.e. the predominant glycolipid found in B.subtilis membrane, which is also used as a membrane anchor for lipoteichoic acid (LTA). Has a role in the biosynthesis of all phosphate-containing envelope polymers, since glucose-1-phosphate is the precursor of UDP-glucose, which serves as a glucosyl donor not only for the biosynthesis of LTA but also for wall teichoic acids (WTAs). Is required fo [...]

pssA
Phosphatidylserine synthase; Evidence 1a: Function experimentally demonstrated in the studied strain; Product type e: enzyme; Belongs to the CDP-alcohol phosphatidyltransferase class-I family.
