From: Structural and functional insights into the mechanism of action of plant borate transporters
Protein sequence alignment of SLC4 family members. AtBOR1 (Acc. Code: OAP07993.1), OsBOR3 (Acc. Code: AK072421), hAE1 (Acc. Code: NP_000333.1), hNBCe1 (Acc Code: NP_003750.1). Only the TM domains of hAE1 and hNBCe1 are aligned with the full length plant BOR proteins. The approximate positions of the TM domains based on the X-ray crystal structure of AtBOR1 (PDB 5L25) are indicated in the cylinders above the sequence. The TM domains are coloured with the helices comprising the core domain in red and the helices comprising the gate domain in blue. The positions of the single point mutations introduced in AtBOR1 are indicated in magenta.
