2.A.40.7.3
The purine transporter Azg1 (takes up 8-azaadenine and 8-azaguanine but not other toxic nucleobase analogues; similar to Azg2 of A. thaliana (Q84MA8); (Mansfield et al. 2009). AZG1 is a cytokinin transporter that interacts with auxin transporter PIN1 (TC# 2.A.69.1.1) and regulates the root stress response (Tessi et al. 2023). The structures and mechanisms of the Arabidopsis cytokinin transporter AZG1 have been determined (Xu et al. 2024).
