CAT5

Gene

CAT5

Protein

Cationic amino acid transporter 5

Organism

Arabidopsis thaliana

Length

569 amino acids

Function

High-affinity permease involved in the transport of the cationic amino acids (e.g. arginine, and, to a lower extent, citrulline and glutamate). Transport mostly basic amino acids, and, to a lower extent neutral and acidic amino acids.

Similarity

Belongs to the amino acid-polyamine-organocation (APC) superfamily. Cationic amino acid transporter (CAT) (TC 2.A.3.3) family.

Protein

Cationic amino acid transporter 5: CAT5

Gene

CAT5

Protein

5-demethoxyubiquinone hydroxylase, mitochondrial

Organism

Saccharomyces cerevisiae (strain ATCC 204508 / S288c)

Length

233 amino acids

Function

Catalyzes the hydroxylation of 2-hexaprenyl-3-methyl-6-methoxy-1,4-benzoquinol (DMQH2) during ubiquinone biosynthesis (PubMed:8621692, PubMed:9452453, PubMed:16624818). Has also a structural role in the COQ enzyme complex, stabilizing COQ3 and COQ4 polypeptides (PubMed:16624818).

Similarity

Belongs to the COQ7 family.
