Contents

Square-shaped octameric structure of KtrA with ATP bound

Function

[KTRA_BACSU] Catalytic subunit of the KtrAB potassium uptake transporter. The 2 major potassium transporter complexes KtrAB and KtrCD confer resistance to both suddenly imposed and prolonged osmotic stress.[1]

About this Structure

4j90 is a 2 chain structure with sequence from Bacillus subtilis subsp. subtilis str. 168. Full crystallographic information is available from OCA.
