RT translocator DiT2.";
RL Plant J. 35:316-331(2003).
CC -!- FUNCTION: Glutamate/malate translocator involved with DIT1 in primary
CC ammonia assimilation and in the re-assimilation of ammonia generated by
CC the photorespiratory pathway. Exports the end product of ammonia
CC assimilation, glutamate, from plastids to the cytosol. The precursor
CC for ammonia assimilation, 2-oxoglutarate, is imported from the cytosol
CC by DIT1. {ECO:0000269|PubMed:12154133, ECO:0000269|PubMed:12887583}.
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=0.41 mM for malate {ECO:0000269|PubMed:12154133};
CC KM=0.23 mM for oxaloacetate {ECO:0000269|PubMed:12154133};
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast inner membrane
CC {ECO:0000305}; Multi-pass membrane protein {ECO:0000305}.
CC -!- TISSUE SPECIFICITY: Expressed in roots, rosette and cauline leaves,
CC stems, flowers and siliques. {ECO:0000269|PubMed:12154133,
CC ECO:0000269|PubMed:12887583}.
CC -!- DISRUPTION PHENOTYPE: Non-viable seedlings under normal atmospheric
CC conditions, but grow normally under non-photorespiratory conditions
CC high CO(2) conditions. {ECO:0000269|PubMed:12154133}.
CC -!- SIMILARITY: Belongs to the SLC13A/DASS transporter (TC 2.A.47) family.
CC DIT1 subfamily. {ECO:0000305}.
