UniProtKB - Q9M024 (TAAC_ARATH)
Protein
Thylakoid ADP,ATP carrier protein, chloroplastic
Gene
TAAC
Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Functioni
Specifically transports adenine nucleotides. Involved in the uptake of ATP into thylakoids in exchange for lumenal ADP.
1 PublicationActivity regulationi
KM and Vmax values toward ATP only are increased by m-chlorocarbonyl cyanide phenylhydrazone (CCCP). The corresponding values for ADP are not affected.1 Publication
Kineticsi
- KM=47 µM for ATP (for the recombinant protein)1 Publication
- KM=0.5 µM for ATP (in vivo)1 Publication
- KM=45 µM for ADP (for the recombinant protein)1 Publication
- Vmax=0.71 nmol/h/mg enzyme toward ATP (for the recombinant protein)1 Publication
- Vmax=0.53 nmol/h/mg enzyme toward ADP (for the recombinant protein)1 Publication

Expressioni
Tissue specificityi
Highly expressed in developing photosynthetic organs such as leaves, flower buds and green siliques. Also detected in roots, flowers, mature leaves and stems.1 Publication
Developmental stagei
Expressed in dark-grown seedlings and remains stable throughout the greening process. Highest expression in developing green tissues and in leaves undergoing senescence or abiotic stress, with the exception of heat shock conditions that induced a drastic reduction of expression.1 Publication
