KtrAB potassium transporter from Bacillus subtilis

Template:ABSTRACT PUBMED 23598340

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] [KTRB_BACSU] Integral membrane 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.[2] [3]

About this Structure

4j7c is a 12 chain structure with sequence from Bacillus subtilis subsp. subtilis str. 168. Full crystallographic information is available from OCA.
