STRINGSTRING
PPT2 protein (Saccharomyces cerevisiae) - STRING interaction network
"PPT2" - Phosphopantetheine:protein transferase in Saccharomyces cerevisiae
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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

PPT2Phosphopantetheine-protein transferase (PPTase), activates mitochondrial acyl carrier protein (Acp1p) by phosphopantetheinylation; Transfers the 4’-phosphopantetheine moiety from coenzyme A to a Ser of mitochondrial acyl-carrier-protein (173 aa)    
Predicted Functional Partners:
FAS1
Beta subunit of fatty acid synthetase, which catalyzes the synthesis of long-chain saturated fatty acids; contains acetyltransacylase, dehydratase, enoyl reductase, malonyl transacylase, and palmitoyl transacylase activities; Fatty acid synthetase catalyzes the formation of long- chain fatty acids from acetyl-CoA, malonyl-CoA and NADPH. The beta subunit contains domains for- [acyl-carrier-protein] acetyltransferase and malonyltransferase, S-acyl fatty acid synthase thioesterase, enoyl-[acyl-carrier-protein] reductase, and 3-hydroxypalmitoyl-[acyl-carrier-protein] dehydratase (2051 aa)
   
   
  0.993
ACC1
Acetyl-CoA carboxylase, biotin containing enzyme that catalyzes the carboxylation of acetyl-CoA to form malonyl-CoA; required for de novo biosynthesis of long-chain fatty acids; Carries out three functions- biotin carboxyl carrier protein, biotin carboxylase and carboxyltransferase. Involved in the synthesis of very-long-chain fatty acid synthesis which is required to maintain a functional nuclear envelope. Required for acylation and vacuolar membrane association of VAC8 which is necessary to maintain a normal morphology of the vacuole (2233 aa)
   
   
  0.989
HFA1
Mitochondrial acetyl-coenzyme A carboxylase, catalyzes the production of malonyl-CoA in mitochondrial fatty acid biosynthesis; Catalyzes the rate-limiting reaction in the mitochondrial fatty acid synthesis (FAS) type II pathway. Responsible for the production of the mitochondrial malonyl-CoA, used for the biosynthesis of the cofactor lipoic acid. This protein carries three functions- biotin carboxyl carrier protein, biotin carboxylase, and carboxyltransferase (2123 aa)
   
   
  0.989
ACP1
Mitochondrial matrix acyl carrier protein, involved in biosynthesis of octanoate, which is a precursor to lipoic acid; activated by phosphopantetheinylation catalyzed by Ppt2p; Carrier of the growing fatty acid chain in fatty acid biosynthesis (By similarity). May be involved in the synthesis of very-long-chain fatty acids. Accessory and non-catalytic subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I), which functions in the transfer of electrons from NADH to the respiratory chain (By similarity) (125 aa)
     
  0.985
FAS2
Alpha subunit of fatty acid synthetase, which catalyzes the synthesis of long-chain saturated fatty acids; contains the acyl-carrier protein domain and beta-ketoacyl reductase, beta-ketoacyl synthase and self-pantetheinylation activities; Fatty acid synthetase catalyzes the formation of long- chain fatty acids from acetyl-CoA, malonyl-CoA and NADPH. The alpha subunit contains domains for- acyl carrier protein, 3- oxoacyl-[acyl-carrier-protein] reductase, and 3-oxoacyl-[acyl- carrier-protein] synthase. This subunit coordinates the binding of the six beta subunits to the enzyme complex (1887 aa)
   
   
  0.967
DUR1,2
Urea amidolyase, contains both urea carboxylase and allophanate hydrolase activities, degrades urea to CO2 and NH3; expression sensitive to nitrogen catabolite repression and induced by allophanate, an intermediate in allantoin degradation; Hydrolysis of urea to ammonia and CO(2) (1835 aa)
   
   
  0.926
MCT1
Predicted malonyl-CoA-ACP transferase, putative component of a type-II mitochondrial fatty acid synthase that produces intermediates for phospholipid remodeling; Involved in biosynthesis of fatty acids in mitochondria (360 aa)

FOX2
Multifunctional enzyme of the peroxisomal fatty acid beta-oxidation pathway; has 3-hydroxyacyl-CoA dehydrogenase and enoyl-CoA hydratase activities; Second trifunctional enzyme acting on the beta-oxidation pathway for fatty acids, possessing hydratase-dehydrogenase- epimerase activities. Converts trans-2-enoyl-CoA via D-3- hydroxyacyl-CoA to 3-ketoacyl-CoA (900 aa)
   
   
  0.695
PPT1
Protein serine/threonine phosphatase with similarity to human phosphatase PP5; present in both the nucleus and cytoplasm; expressed during logarithmic growth; computational analyses suggest roles in phosphate metabolism and rRNA processing; Protein phosphatase that specifically binds to and dephosphorylates the molecular chaperone Hsp90 (HSC82 and HSP82). Dephosphorylation positively regulates the Hsp90 chaperone machinery (513 aa)
