NhaD Na+(Li+)/H+ antiporter (Liu et al., 2005).  AaNhaD is from the soda lake alkaliphile, Alkalimonas amylolytica, is crucial for the bacterium's resistance to salt/alkali stresses (Zhong et al. 2012).

*2.A.62.1.5









Sodium/proton antiporter, NhaD1, of 488 aas and 14 TMSs. Two NhaD homologues that catalyze Na+/H+ antiport were identified from this halotolerant and alkaliphilic strain isolated from sodium enriched black liquor. They exhibit 72% identity and have similar binding affinities for Na+ and Li+, while having different pH profiles. Ha-NhaD1 was active at pH 6.0 and most active at pH 8.0-8.5, whereas Ha-NhaD2 lacked activity at pH 6.0 but exhibited maximal activity at pH 9.5 or higher. Residues involved in transport were identified (Cui et al. 2016).
