STRINGSTRING
BIO4 protein (Saccharomyces cerevisiae) - STRING interaction network
"BIO4" - Dethiobiotin synthetase, catalyzes the third step in the biotin biosynthesis pathway 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

BIO4Dethiobiotin synthetase, catalyzes the third step in the biotin biosynthesis pathway; BIO4 is in a cluster of 3 genes (BIO3, BIO4, and BIO5) that mediate biotin synthesis; expression appears to be repressed at low iron levels (237 aa)    
Predicted Functional Partners:
BIO3
7,8-diamino-pelargonic acid aminotransferase (DAPA), catalyzes the second step in the biotin biosynthesis pathway; BIO3 is in a cluster of 3 genes (BIO3, BIO4, and BIO5) that mediate biotin synthesis; Catalyzes the transfer of the alpha-amino group from S- adenosyl-L-methionine (SAM) to 7-keto-8-aminopelargonic acid (KAPA) to form 7,8-diaminopelargonic acid (DAPA). It is the only animotransferase known to utilize SAM as an amino donor (480 aa)
 
 
  0.999
BIO2
Biotin synthase, catalyzes the conversion of dethiobiotin to biotin, which is the last step of the biotin biosynthesis pathway; complements E. coli bioB mutant (375 aa)
 
 
  0.999
BIO5
Putative transmembrane protein involved in the biotin biosynthesis; responsible for uptake of 7-keto 8-aminopelargonic acid; BIO5 is in a cluster of 3 genes (BIO3, BIO4, and BIO5) that mediate biotin synthesis; Transport into the cell of 7-keto 8-aminopelargonic acid (561 aa)
   
   
  0.991
YJR154W
Putative protein of unknown function; green fluorescent protein (GFP)-fusion protein localizes to the cytoplasm (346 aa)
     
   
  0.930
AAD10
Putative aryl-alcohol dehydrogenase; similar to P. chrysosporium aryl-alcohol dehydrogenase; mutational analysis has not yet revealed a physiological role (288 aa)
     
        0.916
VHT1
High-affinity plasma membrane H+-biotin (vitamin H) symporter; mutation results in fatty acid auxotrophy; 12 transmembrane domain containing major facilitator subfamily member; mRNA levels negatively regulated by iron deprivation and biotin; Involved in uptake of biotin with the concomitant entry of protons (593 aa)
     
 
  0.894
BPL1
Biotin-apoprotein ligase, covalently modifies proteins with the addition of biotin, required for acetyl-CoA carboxylase (Acc1p) holoenzyme formation; Post-translational modification of specific protein by attachment of biotin. Acts on various carboxylases such as acetyl- CoA-carboxylase, pyruvate carboxylase, propionyl CoA carboxylase, and 3-methylcrotonyl CoA carboxylase (690 aa)
   
 
  0.874
TRM9
tRNA methyltransferase, catalyzes esterification of modified uridine nucleotides in tRNA(Arg3) and tRNA(Glu), likely as part of a complex with Trm112p; deletion confers resistance to zymocin; Required for the methylation of the wobble bases at position 34 in tRNA. Appears to have a role in stress-response (279 aa)
   
 
  0.771
OMS1
Protein integral to the mitochondrial membrane; has a conserved methyltransferase motif; multicopy suppressor of respiratory defects caused by OXA1 mutations; Mitochondrial methyltransferase which suppresses respiratory defects caused by OXA1 mutations when overexpressed (471 aa)
   
 
  0.771
BUD23
Methyltransferase, methylates residue G1575 of 18S rRNA; required for rRNA processing and nuclear export of 40S ribosomal subunits independently of methylation activity; diploid mutant displays random budding pattern; S-adenosyl-L-methionine-dependent methyltransferase that specifically methylates the N(7) position of guanine 1575 (m7G1575) in 18S rRNA. Requires the methyltransferase adapter protein TRM112 for full rRNA methyltransferase activity. Important for biogenesis end export of the 40S ribosomal subunit independent on its methyltransferase activity. Required for efficient cleav [...] (275 aa)
