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

A0A0K9Q2L7Ubiquinone biosynthesis protein COQ4 homolog, mitochondrial; Component of the coenzyme Q biosynthetic pathway. May play a role in organizing a multi-subunit COQ enzyme complex required for coenzyme Q biosynthesis. Required for steady-state levels of other COQ polypeptides; Belongs to the COQ4 family. (226 aa)    
Predicted Functional Partners:
ZOSMA_20G00730
Ubiquinone biosynthesis protein; Lipid-binding protein involved in the biosynthesis of coenzyme Q, also named ubiquinone, an essential lipid-soluble electron transporter for aerobic cellular respiration.
    
 
 0.848
COQ3
Ubiquinone biosynthesis O-methyltransferase, mitochondrial; O-methyltransferase that catalyzes the 2 O-methylation steps in the ubiquinone biosynthetic pathway; Belongs to the class I-like SAM-binding methyltransferase superfamily. UbiG/COQ3 family.
    
 
 0.749
ZOSMA_1G02580
Magnesium protoporphyrin IX methyltransferase.
    
 
 0.747
COQ6
Ubiquinone biosynthesis monooxygenase COQ6, mitochondrial; FAD-dependent monooxygenase required for the C5-ring hydroxylation during ubiquinone biosynthesis. Catalyzes the hydroxylation of 3-polyprenyl-4-hydroxybenzoic acid to 3-polyprenyl- 4,5-dihydroxybenzoic acid. The electrons required for the hydroxylation reaction may be funneled indirectly from NADPH via a ferredoxin/ferredoxin reductase system to COQ6.

ABC1 protein.
    
 
 0.612
COQ5
2-methoxy-6-polyprenyl-1,4-benzoquinol methylase, mitochondrial; Methyltransferase required for the conversion of 2- polyprenyl-6-methoxy-1,4-benzoquinol (DDMQH2) to 2-polyprenyl-3-methyl- 6-methoxy-1,4-benzoquinol (DMQH2).
    
 
 0.601
MENG
2-phytyl-1,4-beta-naphthoquinone methyltransferase, chloroplastic; Involved in the biosynthesis of phylloquinone (vitamin K1). Methyltransferase required for the conversion of 2-phytyl-1,4-beta- naphthoquinol to phylloquinol.
    
 
 0.566
A0A0K9Q5X7
Methyltransferase; Belongs to the class I-like SAM-binding methyltransferase superfamily. MPBQ/MBSQ MT family.
