2.A.29.23.3
Chloroplast thylakoid ATP/ADP antiporter, TAAC (Thuswaldner et al., 2007; Haferkamp et al., 2011).  Also transports 3'-phosphoadenosine 5'-phosphosulfate (PAPS), made in the mitochondria and exported to the cytoplasm where it is involved in several aspects of sulfur metabolism, including the biosynthesis of thiols, glucosinolates, and phytosulfokines, and therefore also named PAPST1 (Gigolashvili et al. 2012).  Expression of the PAPST1 gene is regulated by the same MYB transcription factors that also regulate the biosynthesis of sulfated secondary metabolites, glucosinolates.
