*2.A.45.1.1









Arsenical resistance efflux pump (exports As(III) and Sb(III) probably as polymers of the hydroxides using an H+ antiport mechanism) (Meng et al., 2004)
Bacteria
Firmicutes
ArsB of Staphylococcus aureus
*2.A.45.2.1









P-protein; possible tyrosine transporter (also called "melanocyte-specific transporter", "oculocutaneous albinism-related protein (Oca2)" and "pink-eyed dilution gene product").  It has been reported to exhibit chloride-selective anion channel activity and to be required for melanin production, possibly by controling melanosome pH (Bellono et al. 2014).
